1 00:00:02,230 --> 00:00:03,670 Hey, guys, what's up? 2 00:00:04,000 --> 00:00:07,150 So in this video, we will solve another industrial problem, one function. 3 00:00:07,780 --> 00:00:09,460 So the problem is very simple. 4 00:00:10,000 --> 00:00:13,390 We have to write a function, write a function. 5 00:00:15,440 --> 00:00:16,010 To of. 6 00:00:19,260 --> 00:00:19,780 NCR. 7 00:00:20,690 --> 00:00:23,280 So what is NCR, so NZEI? 8 00:00:23,370 --> 00:00:29,450 It was an factorial upon and minus Victoria and two of Victoria. 9 00:00:29,900 --> 00:00:32,600 OK, so this is the form love finding NCAR. 10 00:00:34,010 --> 00:00:38,300 So the value of N and art will be given by use it. 11 00:00:38,960 --> 00:00:40,430 So how we can find ends here. 12 00:00:41,000 --> 00:00:44,870 So we have to find first of all, we have to find and factorial. 13 00:00:45,080 --> 00:00:46,660 Then we will find odd factorial. 14 00:00:47,150 --> 00:00:49,430 And then we will find and minus our factory. 15 00:00:49,760 --> 00:00:50,990 And then we will divide. 16 00:00:51,850 --> 00:00:52,080 OK. 17 00:00:52,400 --> 00:00:54,490 And how to find a factorial phone number. 18 00:00:54,980 --> 00:00:55,700 We have sold. 19 00:00:56,000 --> 00:00:56,450 We have. 20 00:00:56,780 --> 00:00:58,440 We have seen it in the last radio. 21 00:00:59,000 --> 00:01:02,030 OK, so the last radio was how to find fact Orlova number. 22 00:01:04,670 --> 00:01:06,560 OK, so they destroyed the gold. 23 00:01:11,200 --> 00:01:19,840 So let us name this filer's function, NTR Nazi Beebee. 24 00:01:37,830 --> 00:01:41,150 So I would take and put two number and and ah. 25 00:01:45,110 --> 00:01:46,200 Now, what do we do? 26 00:01:47,940 --> 00:01:55,980 Let's make a variable answer, which is it goes to let's name the function as an S.. 27 00:01:57,420 --> 00:01:59,850 And it will take two will loose as input. 28 00:02:00,180 --> 00:02:06,540 And and so NCAR is a function and what it will give me. 29 00:02:07,500 --> 00:02:12,930 And it will give me the value of NCAR to see out answer. 30 00:02:14,690 --> 00:02:16,680 Now let us implement NCAR function. 31 00:02:20,690 --> 00:02:22,400 So they're done by I will be. 32 00:02:22,700 --> 00:02:25,370 And because I have to return an integer value. 33 00:02:25,730 --> 00:02:30,410 So end and see what it will take to number as input. 34 00:02:31,040 --> 00:02:33,890 So end and and. 35 00:02:37,120 --> 00:02:38,240 And what we have to do. 36 00:02:39,590 --> 00:02:40,490 We have to redone. 37 00:02:44,400 --> 00:02:45,720 Factory love and. 38 00:02:48,890 --> 00:02:53,930 Divided by Victoria, Love and minus. 39 00:02:56,320 --> 00:02:58,910 And to Victoria Love. 40 00:03:00,650 --> 00:03:02,000 And now what we have to do. 41 00:03:02,090 --> 00:03:07,190 We have to implement a function that will find the Victrola phone number, which we have done in the 42 00:03:07,280 --> 00:03:08,030 last class. 43 00:03:08,570 --> 00:03:10,550 So this was the code. 44 00:03:11,490 --> 00:03:12,100 Let's cooperate. 45 00:03:13,730 --> 00:03:14,990 And where's your typist? 46 00:03:15,590 --> 00:03:17,110 So I'm calling function fact. 47 00:03:17,420 --> 00:03:20,490 So it should be placed above NCAR. 48 00:03:22,100 --> 00:03:22,300 OK. 49 00:03:22,490 --> 00:03:24,470 So I think our code is ready. 50 00:03:25,370 --> 00:03:31,460 So what I'm doing here is I am taking Tuvalu's as input and I'm calling the function ncar. 51 00:03:31,880 --> 00:03:39,650 So NCAR function to the value of NCI equals and factorial divided by and minus factorial and two are 52 00:03:39,770 --> 00:03:40,370 factorial. 53 00:03:41,640 --> 00:03:41,810 OK. 54 00:03:42,260 --> 00:03:43,610 So this function is calling. 55 00:03:44,750 --> 00:03:48,050 Fact, function, vectorial function to find these factorial. 56 00:03:49,010 --> 00:03:50,150 Okay, so how it works. 57 00:03:51,340 --> 00:03:53,990 First of all, I was I was having Maine. 58 00:03:54,550 --> 00:03:58,150 Men will call NCAR and see, I will call fact. 59 00:03:59,610 --> 00:04:00,760 Three times it will qualify. 60 00:04:01,020 --> 00:04:04,490 Two times, first four and then four and minus eight, then foot out. 61 00:04:05,130 --> 00:04:11,610 So for the first time, let's say for N it will LoDo work and it will redonda value to NCEA. 62 00:04:12,930 --> 00:04:21,240 So caustic would look something like this then and say, I will again call fact for calculating N minus 63 00:04:21,240 --> 00:04:27,510 R, then after calculating and returning the value of and minus eight factorial, the NCAR function 64 00:04:28,110 --> 00:04:30,330 will again call fact function. 65 00:04:30,720 --> 00:04:31,290 So effect. 66 00:04:32,280 --> 00:04:33,500 And it will be done differently. 67 00:04:33,650 --> 00:04:33,950 Love. 68 00:04:34,130 --> 00:04:34,370 Ah. 69 00:04:35,790 --> 00:04:36,660 Now what will happen. 70 00:04:37,020 --> 00:04:40,380 I will execute NCR so I have all the way loose. 71 00:04:40,590 --> 00:04:43,170 I have value off and factorial and minus of victory. 72 00:04:43,200 --> 00:04:43,860 Of victory. 73 00:04:44,160 --> 00:04:45,900 Now I will have done so. 74 00:04:45,990 --> 00:04:48,090 I will have done the answer to mean. 75 00:04:48,740 --> 00:04:50,130 Now what men will do. 76 00:04:50,490 --> 00:04:56,950 So the court was in town so it was NCAR and Gomaa and Main was printing the out answer. 77 00:04:57,660 --> 00:05:02,080 So meanwhile, the words work and after it will hurt, return zero treatment. 78 00:05:02,790 --> 00:05:06,540 Men will be bombed out and my stead becomes empty. 79 00:05:07,740 --> 00:05:10,410 Okay, now this is my entire code. 80 00:05:13,090 --> 00:05:13,720 Let's check. 81 00:05:15,940 --> 00:05:22,190 So I suppose the of friend is five and the value of foresty some outproduce coming out to. 82 00:05:22,660 --> 00:05:25,570 Then let's see whether my output is correct or not. 83 00:05:26,440 --> 00:05:35,560 So I have to calculate five C three, which is five factorial upon five minus three factorial. 84 00:05:36,710 --> 00:05:38,160 And do t factorial. 85 00:05:39,670 --> 00:05:45,130 OK, so five factorial is one twenty two factorial and three factorial. 86 00:05:45,670 --> 00:05:49,480 So when 20 were this two factorial, two were this two factorial. 87 00:05:49,750 --> 00:05:50,170 Six. 88 00:05:50,760 --> 00:05:53,370 So two sixty six then. 89 00:05:53,830 --> 00:05:54,640 So I put this. 90 00:05:54,680 --> 00:05:54,970 Ten. 91 00:05:56,510 --> 00:05:56,760 OK. 92 00:05:56,880 --> 00:05:57,700 So I'm out for this. 93 00:05:57,810 --> 00:05:58,210 Correct. 94 00:06:01,760 --> 00:06:04,280 Now, one more thing that I want to again clarify is. 95 00:06:06,960 --> 00:06:13,120 This and this are they both are different from this end and decide. 96 00:06:14,570 --> 00:06:14,840 Why? 97 00:06:14,930 --> 00:06:16,700 Because their scopes are different. 98 00:06:17,090 --> 00:06:22,030 So here, if you change the value of n supposed to and you will make ah, let's say three. 99 00:06:22,520 --> 00:06:25,460 They will not be any effect on the values of an NDR. 100 00:06:27,490 --> 00:06:27,760 OK. 101 00:06:28,090 --> 00:06:34,750 Similarly, this answer variable and this answer very well, they are completely different because they 102 00:06:34,750 --> 00:06:35,950 have different scope. 103 00:06:38,410 --> 00:06:42,610 Now, one more time you can see reusability of function. 104 00:06:42,720 --> 00:06:44,850 We are using the code. 105 00:06:45,340 --> 00:06:49,210 OK, so this is the main advantage of using functions. 106 00:06:51,120 --> 00:06:51,320 OK. 107 00:06:52,690 --> 00:06:54,850 So if you have any doubt, feel free to ask. 108 00:06:55,300 --> 00:06:55,820 Thank you.
