I have been trying this problem using C++, but have been unable to solve it. I tried doing in Python3 and it did fine on my Linux Machine, but when I submit it here, its shows me run-time error. Where am I going wrong?

The Code: a = int(input()) b = int(input()) ans = (a ** b) — (b ** a) print((ans))
