Given two large numbers as strings, find if one is the power of another. For Example :
Input : a = "374747", b = "52627712618930723" Output : YES Explanation : 374747^3 = 52627712618930723 Input : a = "2", b = "4099" Output : NO
Prerequisite : Multiply two large numbers represented as string
The approach is simple. First, find smaller of the two strings and then multiply it with itself until it becomes equal to or greater than the larger string. If they are equal, return true, else return false.
Below is the implementation of above approach
