If you are new to learning programming and do not know where to start, please try Problem A “Welcome to AtCoder” from practice contest. There you can find a sample code for each language.

This problem can be solved by switching a conditional branch on whether the conditions in the problem statement are satisfied or not.

Sample Code (C++)

#include <bits/stdc++.h>

int ri() {
	int n;
	scanf("%d", &n);
	return n;
}

int main() {
	int a = ri();
	int b = ri();
	int c = ri();
	if (a * a + b * b < c * c) puts("Yes");
	else puts("No");
	return 0;
}

Sample Code (Python)

a, b, c = map(int, input().split())

if a * a + b * b < c * c : print('Yes')
else : print('No')
