What is a code to check if a number can be expressed as sum of two Perfect powers and the other steps required given the following:
Check if a number can be expressed as sum of two Perfect powers | Function that returns true if n can be written as a ^ m + b ^ n.
Taking isSum boolean array for check the sum exist or not.
To store perfect squares.
Initially all sums as false.
If sum exist then push that sum into perfect square vector.
Mark all perfect powers as false.
Traverse each perfectPowers.
Calculating Sum with perfect powers array.
Given Number n.
