Description

A powerful integer equals xⁱ + y^j for some non-negative i and j. Given x, y, and an upper limit bound, return a deduplicated list of all powerful integers that do not exceed bound.

Example 1:

Input: x = 2, y = 3, bound = 10

Output: [2,3,4,5,7,9,10]

Explanation:

2 = 20 + 30

3 = 21 + 30

4 = 20 + 31

5 = 21 + 31

7 = 22 + 31

9 = 23 + 30

10 = 20 + 32

Example 2:

Input: x = 3, y = 5, bound = 15

Output: [2,4,6,8,10,14]
