题目标签:HashMap 题目让我们找出所有独一的powerful integers 小于bound的情况下. 把 x^i 看作 a:把 y^j 看作b, 代入for loop,把所有的情况都遍历一遍. 参考的这种方法,用for loop 写的比较简洁易懂. 具体看code. Java Solution: Runtime: 4 ms, faster than 99.85% Memory Usage: 37.5 MB, less than 7.69% 完成日期:03/13/2019 关键点:把 x…

题目如下: Given two non-negative integers x and y, an integer is powerful if it is equal to x^i + y^j for some integers i >= 0 and j >= 0. Return a list of all powerful integers that have value less than or equal to bound. You may return the answer in a…

Given two non-negative integers x and y, an integer is powerful if it is equal to x^i + y^j for some integers i >= 0 and j >= 0. Return a list of all powerful integers that have value less than or equal to bound. You may return the answer in any ord…

这道题是LeetCode里的第970道题. 题目描述: 给定两个正整数 x 和 y,如果某一整数等于 x^i + y^j,其中整数 i >= 0 且 j >= 0,那么我们认为该整数是一个强整数. 返回值小于或等于 bound 的所有强整数组成的列表. 你可以按任何顺序返回答案.在你的回答中,每个值最多出现一次. 示例 1: 输入:x = 2, y = 3, bound = 10 输出:[2,3,4,5,7,9,10] 解释: 2 = 2^0 + 3^0 3 = 2^1 + 3^0 4 = 2…
