EXAMPLE

Example

Input

3 5

Output

34

LIMITS

Constraints

|a|, |b| ≤ 10^9. The answer fits in signed 64-bit integer.

LEARN Theory for this problem

+

Use `long long` for integer arithmetic when products may exceed 32-bit `int`.

Connection to “Sum of Two Squares”: here, intermediate values are best kept in named variables so the formula stays readable and data types remain clear.

#include <iostream>
using namespace std;
int main() {
    long long a, b;
    cin >> a >> b;
    long long result = a * a + b * b;
    cout << result << '\n';
    return 0;
}
