In this problem, we are given a code snippet, and from that code snippet, we have to determine what the instruction f7 will evaluate.
00:14
So first, let's see the code snippet.
00:16
So we have a function that's having int as the return type.
00:21
So int f, int, n, that's the argument here.
00:25
And we have a variable of integer type that's answer.
00:28
This is set to zero initially.
00:30
And we have a far loop and the variable i, this starts from 1 and it continues till n.
00:39
And here we increment i.
00:42
And the instruction that we have here is if i is less than n by 2, in that case, answer here will be equal to answer minus i.
00:54
And in all other cases, answer will be incremented by i.
00:59
And at the end we just return answer.
01:06
So first let's see here that when we are talking about the instruction f7, that means we are passing 7 as the value of n.
01:16
So let's keep track of i and answer.
01:23
So first, the value of i, this is set to 1 and the answer is 0.
01:28
And now this condition here, this is n by 2, which means we are talking about 7 by 2, and since i is of type in tier, it means that this will be three in integer form.
01:40
So this condition will be evaluated till the time i does not reach 3.
01:45
So we will write that here.
01:47
So when i is 1, answer here is 0...
