1 00:00:01,360 --> 00:00:03,040 Hey, guys, what's up? 2 00:00:03,580 --> 00:00:07,930 So today we are going to solve one more interesting pattern printing problem. 3 00:00:08,830 --> 00:00:15,700 So read and read in and we have to print below batton. 4 00:00:18,520 --> 00:00:22,080 So what is the burden so for any cause five. 5 00:00:22,270 --> 00:00:23,380 My pattern is. 6 00:00:24,810 --> 00:00:28,920 One, two, three, two. 7 00:00:30,690 --> 00:00:34,200 Three, four, five, four, three. 8 00:00:35,510 --> 00:00:45,890 Four, five, six, seven, six, five, four, five, six, seven, eight, nine, eight, seven, 9 00:00:46,070 --> 00:00:47,210 six, five. 10 00:00:48,690 --> 00:00:57,570 So if you remember, we have already sold this question and SolarWorld right now, if we will write 11 00:00:57,630 --> 00:01:01,320 the actual C++ code for solving this problem. 12 00:01:02,540 --> 00:01:07,180 So if you're looking at a league of the value of and there's five, I am renting five rows. 13 00:01:08,120 --> 00:01:13,070 OK, so I need a loop and this loop will run and times. 14 00:01:15,230 --> 00:01:19,940 OK, so how many species I have to print, I have to print. 15 00:01:20,390 --> 00:01:22,400 And minus eight species. 16 00:01:23,400 --> 00:01:26,120 OK, so I have to print and minus ice pieces. 17 00:01:27,060 --> 00:01:30,030 So for a year through, I have to print and minus a. 18 00:01:31,390 --> 00:01:33,120 Spaces then. 19 00:01:34,040 --> 00:01:37,640 Now, if you look at it fully, first, I am printing increasing numbers. 20 00:01:38,630 --> 00:01:40,410 So the numbers are increasing. 21 00:01:42,620 --> 00:01:45,680 So how many numbers, how many increasing numbers I have to print? 22 00:01:46,390 --> 00:01:47,910 So if the value of AI is five. 23 00:01:47,990 --> 00:01:49,970 I am printing five increasing numbers. 24 00:01:50,540 --> 00:01:51,410 So I have to print. 25 00:01:51,720 --> 00:02:00,290 I see increasing numbers from where to start starting from. 26 00:02:01,720 --> 00:02:03,000 Starting from I. 27 00:02:03,620 --> 00:02:09,180 So if you look carefully at the value of Phase five to the first number is five, if the value of AI 28 00:02:09,180 --> 00:02:10,790 is for the first number is. 29 00:02:11,390 --> 00:02:13,420 For now after this. 30 00:02:13,480 --> 00:02:15,460 I have to print decreasing numbers. 31 00:02:16,960 --> 00:02:18,960 I have to print decreasing numbers. 32 00:02:19,300 --> 00:02:21,370 So how many decreasing numbers I have to print. 33 00:02:21,940 --> 00:02:25,660 So if the value of I is four, I am printing three decreasing numbers. 34 00:02:26,260 --> 00:02:30,070 If the value of I use five, I am printing for decreasing numbers. 35 00:02:30,970 --> 00:02:34,900 So I have to print I minus one. 36 00:02:35,410 --> 00:02:37,310 Decreasing numbers. 37 00:02:39,360 --> 00:02:47,400 Now, from where to start, so the value of ICE five, I am starting from eight, which is the way minus 38 00:02:47,640 --> 00:02:47,910 two. 39 00:02:48,240 --> 00:02:49,830 Similarly, the value of AI is four. 40 00:02:49,920 --> 00:02:54,340 I am starting from six, which is the way minus two. 41 00:02:54,960 --> 00:02:55,810 So I am minus one. 42 00:02:55,830 --> 00:03:03,450 The closing numbers starting from the way minus two. 43 00:03:04,140 --> 00:03:06,790 Now w we have printed the entire row. 44 00:03:06,840 --> 00:03:10,830 When I printed the end bad I year through I have to go to next to lose. 45 00:03:10,890 --> 00:03:14,480 So I will print C out and lane. 46 00:03:15,330 --> 00:03:18,210 So in total how many loops do I need here. 47 00:03:18,840 --> 00:03:28,620 So I need one outer loop, one loop, four spaces, one loop for printing increasing numbers and when 48 00:03:28,620 --> 00:03:30,780 loop for printing decreasing numbers. 49 00:03:31,800 --> 00:03:32,010 OK. 50 00:03:32,160 --> 00:03:42,900 So in total I will need four loops out of which one loop is outer loop and the other three loops are 51 00:03:43,020 --> 00:03:43,530 in a loop. 52 00:03:46,030 --> 00:03:46,270 OK. 53 00:03:46,510 --> 00:03:49,960 So I think their logic and the problem is clear. 54 00:03:50,590 --> 00:03:51,610 So let say I called. 55 00:03:54,540 --> 00:03:56,450 So let us name this violence. 56 00:03:57,690 --> 00:04:00,460 No pattern to sue. 57 00:04:04,170 --> 00:04:07,320 Badon do not see BP. 58 00:04:23,120 --> 00:04:29,120 So first so first let us dig in, Burt Fundi User. 59 00:04:29,180 --> 00:04:34,910 So inten seen and seen. 60 00:04:35,000 --> 00:04:37,550 And now we have decided that. 61 00:04:39,090 --> 00:04:43,950 So first, I have to run a loop and times so fun. 62 00:04:44,190 --> 00:04:57,070 So for running a loop and times and time equals one while I is less than or equal to N and here I. 63 00:04:57,210 --> 00:04:57,780 Plus plus. 64 00:04:58,500 --> 00:04:59,550 So with the help of. 65 00:05:00,550 --> 00:05:08,840 These tea I when I left English to end and I plus plus this loop is going to run and times. 66 00:05:09,040 --> 00:05:11,410 Now each time this loop is running, I will print. 67 00:05:11,700 --> 00:05:12,110 I through. 68 00:05:12,940 --> 00:05:19,230 So for printing the ideal first I have to print and minus I space's ok. 69 00:05:19,510 --> 00:05:21,110 And minus ice pieces. 70 00:05:22,660 --> 00:05:35,800 So and Spees equals one vile space is less than or equal to two and minus eight pieces. 71 00:05:35,840 --> 00:05:38,680 So N minus I space's. 72 00:05:41,250 --> 00:05:44,760 Space plus space plus, plus. 73 00:05:46,200 --> 00:05:51,120 Now this loop will run and minus eight times, and each time this loop is running. 74 00:05:51,810 --> 00:05:54,120 What I will do, I will print a space. 75 00:05:57,270 --> 00:06:05,690 OK, so after printing spaces, what I have to do, I have to print I increasing numbers starting from 76 00:06:05,870 --> 00:06:09,500 I I increasing numbers starting from my. 77 00:06:09,590 --> 00:06:11,120 That means I need. 78 00:06:14,480 --> 00:06:20,200 So that means I need a loop and this loop will run eight times. 79 00:06:21,410 --> 00:06:25,660 Also, I need a value visual initially B I. 80 00:06:25,820 --> 00:06:30,500 Because you can see here, if the value of eyes for the first number that I have to print is four. 81 00:06:30,770 --> 00:06:32,570 So initially value equals I. 82 00:06:33,350 --> 00:06:35,570 And you can see here four. 83 00:06:35,630 --> 00:06:37,520 Then five, then six and then seven. 84 00:06:38,120 --> 00:06:42,140 So each time I am printing the value I will increase the value by one. 85 00:06:43,160 --> 00:06:45,230 So I at times I loop. 86 00:06:45,680 --> 00:06:49,940 Each time I will print so out value. 87 00:06:50,360 --> 00:06:51,260 Initially the values. 88 00:06:51,380 --> 00:06:52,760 I add value plus. 89 00:06:52,760 --> 00:06:53,090 Plus. 90 00:06:54,790 --> 00:06:55,770 So eight times. 91 00:06:55,860 --> 00:06:58,310 OK, so let's stick. 92 00:07:00,010 --> 00:07:04,240 So end value equals I. 93 00:07:04,630 --> 00:07:06,370 Because we have to start printing from. 94 00:07:06,490 --> 00:07:09,760 I know how many increasing numbers I. 95 00:07:09,880 --> 00:07:10,840 Increasing numbers. 96 00:07:10,960 --> 00:07:16,070 So end count equals one. 97 00:07:18,070 --> 00:07:23,180 While ground is less than or equal to how many. 98 00:07:23,230 --> 00:07:29,660 Using numbers I increasing numbers count plus plus. 99 00:07:30,370 --> 00:07:36,120 So each time this loop is running what I will do I will see out value. 100 00:07:36,660 --> 00:07:41,070 Now after printing that value, I have to increase the value by one. 101 00:07:42,630 --> 00:07:42,910 OK. 102 00:07:43,870 --> 00:07:47,530 So this loop is for printing the numbers in increasing orders. 103 00:07:48,460 --> 00:07:49,240 You can see here. 104 00:07:51,670 --> 00:07:53,580 So I have to run the loop eight times. 105 00:07:54,160 --> 00:08:00,220 So what I did, I take a variable count, which is initially one that I check counted less than I close 106 00:08:00,220 --> 00:08:00,720 to I. 107 00:08:00,820 --> 00:08:03,450 And then I did count plus plus. 108 00:08:03,880 --> 00:08:07,000 And each time this loop is running, I am printing value. 109 00:08:07,690 --> 00:08:10,210 And then I am increasing the value by when. 110 00:08:11,530 --> 00:08:20,040 So then then now I have to print a minus one, the closing numbers, I'm minus one, negative numbers. 111 00:08:20,770 --> 00:08:22,240 So for running. 112 00:08:22,300 --> 00:08:24,700 So I need a loop and this loop will run. 113 00:08:24,970 --> 00:08:28,400 How many number of times I minus one names. 114 00:08:29,440 --> 00:08:30,940 So I loop for running. 115 00:08:31,540 --> 00:08:34,660 So we need a loop that will run a minus one times. 116 00:08:34,960 --> 00:08:36,240 So what is the starting value. 117 00:08:37,150 --> 00:08:40,660 So starting value is the way minus two. 118 00:08:41,190 --> 00:08:41,710 Four, five. 119 00:08:41,750 --> 00:08:42,190 The starting. 120 00:08:42,190 --> 00:08:42,790 We lose it. 121 00:08:42,910 --> 00:08:44,140 Which is way minus two. 122 00:08:44,700 --> 00:08:47,530 Its value is initially the way minus two. 123 00:08:48,490 --> 00:08:48,710 Okay. 124 00:08:48,820 --> 00:08:52,840 And each time I am printing the value the value is decreased. 125 00:08:52,930 --> 00:08:54,640 Eight, seven, six and five. 126 00:08:54,700 --> 00:08:55,600 So what I will do. 127 00:08:56,320 --> 00:09:00,220 Value minus minus because the values are decreasing. 128 00:09:01,460 --> 00:09:05,740 So I am minus one times and the first we lose at the way minus two. 129 00:09:09,040 --> 00:09:11,210 So the first value. 130 00:09:13,120 --> 00:09:19,090 So the first value is to a minus two. 131 00:09:19,810 --> 00:09:21,730 And how many times I have to run the loop? 132 00:09:23,130 --> 00:09:24,360 A minus one times. 133 00:09:24,420 --> 00:09:32,790 So consequence one way count is less than or close to a minus one times. 134 00:09:32,820 --> 00:09:38,060 We have two in the loop so count plus plus. 135 00:09:38,880 --> 00:09:46,910 Now, each time this loop is learning, I have to see out value since the numbers are printed in the 136 00:09:46,910 --> 00:09:47,670 closing order. 137 00:09:48,300 --> 00:09:51,570 So value will be diclemente by one. 138 00:09:51,570 --> 00:09:53,070 So value minus minus. 139 00:09:54,240 --> 00:09:55,680 Now we have printed the spaces. 140 00:09:55,740 --> 00:09:57,330 We have been today increasing numbers. 141 00:09:57,360 --> 00:09:59,070 We have been decreasing the most. 142 00:10:00,030 --> 00:10:02,930 Now it is the right time to go to next line. 143 00:10:02,960 --> 00:10:04,440 So see out and line. 144 00:10:05,670 --> 00:10:07,230 So this is the complete. 145 00:10:09,040 --> 00:10:09,400 Called. 146 00:10:17,090 --> 00:10:20,780 OK, so this loop is for printing spaces. 147 00:10:22,280 --> 00:10:28,340 This loop is for printing increasing numbers and this loop is for printing decreasing numbers. 148 00:10:28,400 --> 00:10:29,600 OK, so let me write here. 149 00:10:36,820 --> 00:10:39,010 For spaces. 150 00:10:43,660 --> 00:10:48,940 Now, this is forward, increasing numbers. 151 00:10:52,440 --> 00:10:59,190 And this loop is for the closing numbers. 152 00:11:00,840 --> 00:11:01,120 OK. 153 00:11:01,710 --> 00:11:04,230 So let us test our program, how it is working. 154 00:11:08,540 --> 00:11:15,410 Let's say the value of this five, some output is correct, one down to three. 155 00:11:15,500 --> 00:11:19,760 In closing order, three, four, five, including order four, five, six, seven, inclosing order 156 00:11:20,300 --> 00:11:23,960 five, six, seven, eight, nine, including order and then decreasing orders. 157 00:11:25,180 --> 00:11:25,450 OK. 158 00:11:27,030 --> 00:11:29,930 Lettuce tested for more will lose. 159 00:11:32,410 --> 00:11:34,160 Let's say an enclosed tree. 160 00:11:35,960 --> 00:11:36,200 OK. 161 00:11:36,370 --> 00:11:39,400 So our court is a hundred percent correct. 162 00:11:41,970 --> 00:11:42,230 OK. 163 00:11:44,960 --> 00:11:46,280 So that is it for this video. 164 00:11:46,670 --> 00:11:47,190 Thank you.
