Solution: Powerful Integers
Explore how to identify all powerful integers less than or equal to a given bound using hash maps and nested loops. Understand handling exponential growth of powers, and special cases when bases equal one. This lesson helps you develop an optimal solution with efficient time and space complexity analysis suitable for coding interviews.

Statement
Given three integers x, y, and bound, return a list of all powerful integers whose value is less than or equal to bound.
An integer is considered powerful if it can be expressed as xy
