here is my code:

include <bits/stdc++.h>

using namespace std;

int main() { double a,b; double sum=0;

cin >> a>>b;

sum = pow(a,b)-pow(b,a); cout << sum<< endl; return 0; }

why it is showing wrong answer on test 5 no matter whay i do.

Consider the input 99 100. Note that both pow(99, 100) and pow(100, 99) will overflow the limits of int or even long long int in C++. So you could solve this problem using big integers. For example, in python you can simply submit:

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

print(a**b - b**a)
