1 00:00:01,280 --> 00:00:03,200 Hey, guys, what's up? 2 00:00:03,800 --> 00:00:08,750 So today we are going to solve one more interesting pattern, printing problem. 3 00:00:09,830 --> 00:00:13,160 So write a program to print. 4 00:00:17,260 --> 00:00:18,210 Below baktun. 5 00:00:19,340 --> 00:00:21,920 So four and equals five. 6 00:00:21,950 --> 00:00:23,930 My pattern would look something like. 7 00:00:33,390 --> 00:00:33,600 OK. 8 00:00:33,690 --> 00:00:34,960 So four and equals five. 9 00:00:34,990 --> 00:00:37,060 I have to print this pattern. 10 00:00:37,990 --> 00:00:42,520 We have not solved this question before, so let us all discussion for the first time. 11 00:00:43,510 --> 00:00:51,370 So here the real fight is when I used to I used three, I use four and I use five. 12 00:00:52,060 --> 00:00:53,350 So one thing is very clear here. 13 00:00:53,470 --> 00:01:00,070 I need a loop that will run and times because you can see here the value of this fire if I am printing 14 00:01:00,070 --> 00:01:00,610 five rules. 15 00:01:00,700 --> 00:01:03,640 So I need a loop and this loop will run and times. 16 00:01:04,710 --> 00:01:07,410 Okay, now one more thing that we here. 17 00:01:07,880 --> 00:01:09,450 If the value of fire is too. 18 00:01:09,750 --> 00:01:12,960 I am beginning to lose the value of history. 19 00:01:13,230 --> 00:01:14,280 I am renting three. 20 00:01:14,280 --> 00:01:15,990 We're losing the value of I is four. 21 00:01:16,020 --> 00:01:18,120 I am renting for values and so on. 22 00:01:19,390 --> 00:01:25,750 OK, so one thing is very clear here, footprinting a year through for printing, a year through. 23 00:01:26,100 --> 00:01:27,780 I have to print a numbers. 24 00:01:30,470 --> 00:01:30,750 OK. 25 00:01:31,940 --> 00:01:41,530 So Androes for printing, I for printing, I drew through, I need I need to print eye numbers. 26 00:01:43,280 --> 00:01:46,830 One more thing here that we are, we have observed this. 27 00:01:47,540 --> 00:01:53,510 If I is even if I easy when I am starting from zero. 28 00:01:53,750 --> 00:01:59,150 So we can see if the value of AI is even the first number is zero of the value of AI is even the first 29 00:01:59,150 --> 00:02:00,140 number is zero. 30 00:02:01,070 --> 00:02:09,680 And if the value of AI is on, my first number is when, when and when, if the value of AI is odd. 31 00:02:12,110 --> 00:02:19,460 So if the value of AI is odd, I will start printing AI yetto from when, otherwise I will start printing 32 00:02:19,460 --> 00:02:25,070 from zero and I have to print AI numbers and each time I have to change the number. 33 00:02:25,520 --> 00:02:28,400 If I have print zero nine next time I will print one. 34 00:02:28,820 --> 00:02:30,050 Next time I will print zero. 35 00:02:30,170 --> 00:02:31,460 Next time I will print one. 36 00:02:31,790 --> 00:02:35,420 Similarly, if I have printed one, the next time I will print zero. 37 00:02:35,480 --> 00:02:37,010 The next time I will print one. 38 00:02:37,070 --> 00:02:38,690 The next time I will print zero. 39 00:02:39,110 --> 00:02:45,230 So basically they will be swiping between zero and one zero one zero one or one zero one zero. 40 00:02:47,760 --> 00:02:48,150 So. 41 00:02:49,920 --> 00:02:52,580 I equals one vial. 42 00:02:53,430 --> 00:02:59,070 I is less than articles to N and I C++. 43 00:02:59,550 --> 00:03:05,930 So this outer loop is for running the loop and times because we have to print Androes. 44 00:03:07,020 --> 00:03:12,740 Now I will check if I Yeah. 45 00:03:12,760 --> 00:03:19,160 Through is even if they throw on dividing by two gives a window zero that means I is even. 46 00:03:20,220 --> 00:03:22,620 So my first number is going to be zero. 47 00:03:22,980 --> 00:03:30,400 So when two equals zero else we can see my first value is going to be one. 48 00:03:31,380 --> 00:03:31,620 Okay. 49 00:03:31,680 --> 00:03:33,030 So this thing is clear. 50 00:03:33,510 --> 00:03:34,800 And now what we have to do. 51 00:03:35,940 --> 00:03:37,780 We have to print iron ambo's. 52 00:03:39,210 --> 00:03:41,580 We have to print eye numbers. 53 00:03:41,970 --> 00:03:50,970 So since we have to print eight numbers, we need a loop and this loop children eight times so and count 54 00:03:51,320 --> 00:03:52,860 equals one. 55 00:03:54,030 --> 00:03:58,890 While count is less than articles to a 56 00:04:02,790 --> 00:04:03,390 count. 57 00:04:03,910 --> 00:04:04,660 Plus, plus. 58 00:04:05,370 --> 00:04:08,970 And here I will friend my value. 59 00:04:10,770 --> 00:04:12,290 Now I have to change the value. 60 00:04:13,170 --> 00:04:18,180 So what I will do if the value that we have printed is one. 61 00:04:18,630 --> 00:04:20,160 Then make value zero. 62 00:04:20,400 --> 00:04:22,590 Because next time we have to print zero. 63 00:04:23,660 --> 00:04:32,570 Similarly elusive, the value that we have printed now is zero, then make value one, because next 64 00:04:32,570 --> 00:04:34,280 time we have to print one. 65 00:04:35,420 --> 00:04:41,420 So why I am doing this because we have to print alternate zeros and ones. 66 00:04:42,390 --> 00:04:45,110 Okay, so we have to print alternate zeros and ones. 67 00:04:45,410 --> 00:04:48,770 So that's why I am checking if the value that we have printed is one. 68 00:04:49,100 --> 00:04:52,370 Make it zero so that next time I will print zero. 69 00:04:52,760 --> 00:04:56,600 If the value that we have printed now is zero, then make it one. 70 00:04:57,140 --> 00:04:59,930 So that next time we will print one. 71 00:05:01,010 --> 00:05:01,540 Well, guess what? 72 00:05:01,650 --> 00:05:03,390 This is the entire logic. 73 00:05:04,440 --> 00:05:05,970 Now, let us write called. 74 00:05:09,130 --> 00:05:12,190 So let us name this file as. 75 00:05:15,530 --> 00:05:19,600 One zero baktun. 76 00:05:22,480 --> 00:05:22,760 OK. 77 00:05:38,860 --> 00:05:40,620 You know, the first thing that we have to do. 78 00:05:41,130 --> 00:05:46,170 I will take an as and put fundi user simple. 79 00:05:47,220 --> 00:05:54,810 Then I will need a loop that will run and times because I have to print and rose. 80 00:05:59,120 --> 00:06:01,520 Now, this loop will run and times. 81 00:06:02,330 --> 00:06:06,730 Now, first of all, we have to decide which way do we have to print first? 82 00:06:07,490 --> 00:06:18,160 Okay, so if the I yet rule is and even Drew, if the eighth row isn't even true, I will start my first 83 00:06:18,170 --> 00:06:21,170 value that I will print is going to be zero. 84 00:06:22,340 --> 00:06:30,800 Otherwise, as my first value today, I will print is one simple. 85 00:06:32,120 --> 00:06:33,890 So let us make 86 00:06:36,730 --> 00:06:38,910 our variable and will. 87 00:06:39,880 --> 00:06:40,190 Okay. 88 00:06:41,130 --> 00:06:42,200 So you can see here. 89 00:06:46,020 --> 00:06:53,580 So you can see here, if the value of I was too low, if I was even my first number was zero. 90 00:06:53,730 --> 00:06:56,940 If the value of I was offered, my first number was one. 91 00:06:57,390 --> 00:06:59,250 So I have initialized my value. 92 00:07:01,300 --> 00:07:04,210 So I've initialized to my value now what I have to do. 93 00:07:04,690 --> 00:07:12,100 I will run a loop, I Adames, because we have to print eye numbers, okay, because we have to print 94 00:07:12,120 --> 00:07:12,700 a numbers. 95 00:07:12,760 --> 00:07:15,280 So I need a loop that will run eight times. 96 00:07:18,160 --> 00:07:20,830 So let's make a variable and count. 97 00:07:23,650 --> 00:07:26,680 So we have to run the loop eight times. 98 00:07:26,830 --> 00:07:35,550 So count less than or equal to a count plus plus simple. 99 00:07:36,490 --> 00:07:41,770 And now here we have to print sea out value. 100 00:07:42,970 --> 00:07:44,320 But this is not enough. 101 00:07:45,010 --> 00:07:47,130 Where do we have to do after printing that value? 102 00:07:47,260 --> 00:07:49,860 If the value was one, we have to make it zero. 103 00:07:50,200 --> 00:07:52,930 If the value was zero, we have to make it when. 104 00:07:54,270 --> 00:07:54,560 OK. 105 00:07:54,820 --> 00:08:05,770 So if the value that we have printed is one where we have to do make it zero, value equals zero because 106 00:08:05,770 --> 00:08:10,210 we have to print alternate zeros and ones else. 107 00:08:10,220 --> 00:08:15,220 If check if the value net we have printed is zero. 108 00:08:16,960 --> 00:08:22,360 Then we have to make this value one because next time we have to print one. 109 00:08:23,770 --> 00:08:26,320 OK, so this is the end bad logic. 110 00:08:28,680 --> 00:08:30,350 Now, let us based our program. 111 00:08:33,240 --> 00:08:34,550 OK, over here, semicolon. 112 00:08:36,190 --> 00:08:38,100 Now let us test our program. 113 00:08:41,060 --> 00:08:43,010 Let's say, and there's three. 114 00:08:44,730 --> 00:08:46,290 OK, so what is the mistake here? 115 00:08:47,560 --> 00:08:50,270 So the mistake is very common after printing. 116 00:08:50,860 --> 00:08:57,450 So after printing the numbers, after printing one entire drawer, I have to go to next to do so see 117 00:08:57,460 --> 00:08:59,230 out and Lane. 118 00:09:00,190 --> 00:09:01,090 Now, this is correct. 119 00:09:02,530 --> 00:09:03,820 Let's say they're really off. 120 00:09:03,940 --> 00:09:04,870 And there's three. 121 00:09:07,150 --> 00:09:10,440 Again, with outproduce, correct, not a distaste. 122 00:09:10,520 --> 00:09:11,210 One more time. 123 00:09:11,990 --> 00:09:15,170 Let's say the value of an is five. 124 00:09:18,000 --> 00:09:18,870 So now four days. 125 00:09:19,470 --> 00:09:19,860 Correct. 126 00:09:20,370 --> 00:09:20,600 OK. 127 00:09:22,200 --> 00:09:23,880 Now, what you can do is. 128 00:09:25,220 --> 00:09:31,520 So instead of writing this, we can also write like this. 129 00:09:31,640 --> 00:09:34,280 So value equals. 130 00:09:34,470 --> 00:09:36,830 When my nose value. 131 00:09:39,070 --> 00:09:39,310 OK. 132 00:09:39,470 --> 00:09:44,780 So they both ask him this thing and this thing, they bought the same. 133 00:09:46,510 --> 00:09:47,260 Let me show you. 134 00:09:47,830 --> 00:09:54,520 So if the value of an is five, some output is correct. 135 00:09:55,450 --> 00:09:55,720 OK. 136 00:09:56,140 --> 00:09:57,340 So they both are the same. 137 00:09:57,610 --> 00:10:01,330 Now, why the you ask him now? 138 00:10:01,630 --> 00:10:02,860 This thing was obvious. 139 00:10:03,400 --> 00:10:04,450 This thing was obvious. 140 00:10:04,990 --> 00:10:10,390 So what it was doing, if the value is when it will make value equals zero. 141 00:10:10,780 --> 00:10:14,830 Similarly, if the value is zero, it will make value equals one. 142 00:10:15,340 --> 00:10:17,380 Now this line will also do the same book. 143 00:10:18,240 --> 00:10:18,440 OK. 144 00:10:18,550 --> 00:10:22,780 Suppose value equals one minus value. 145 00:10:24,370 --> 00:10:28,900 So first case, suppose the value is initially one. 146 00:10:29,710 --> 00:10:30,970 OK, so put one here. 147 00:10:31,480 --> 00:10:32,770 So one minus one zero. 148 00:10:33,010 --> 00:10:34,660 So new value will become two. 149 00:10:35,830 --> 00:10:37,540 Now suppose the value is initially zero. 150 00:10:37,620 --> 00:10:38,830 Now put zero here. 151 00:10:38,920 --> 00:10:40,630 So value equals one minus zero. 152 00:10:40,900 --> 00:10:42,880 So new value will become one. 153 00:10:43,300 --> 00:10:46,660 So you can see here it is also changing the values. 154 00:10:48,290 --> 00:10:51,970 Obviously, this line and this line, the bow tie. 155 00:10:52,500 --> 00:10:55,030 Same you can write any one of them. 156 00:10:57,780 --> 00:11:04,930 OK, so I recommended this out for the reference that this line and this line. 157 00:11:05,050 --> 00:11:06,720 They're both the same. 158 00:11:07,870 --> 00:11:08,110 OK. 159 00:11:08,920 --> 00:11:10,270 So this is it for this video. 160 00:11:10,450 --> 00:11:10,870 Thank you.
