In a given integer array A, we must move every element of A to either list B or list C. (B and C initially start empty.) Return true if and only if after such a move, it is possible that the average value of B is equal to the average value of C, and B and C are both non...

https://leetcode.com/problems/split-array-with-same-average/ 一个数组,能否分成两部分,使之平均值相同。解题过程很愉快呀。 经过几次转换,变成一个比较简单的题目。 问题1:原始数组a,分成两个子数组a1,a2。a1和a2的均值相同,则必须等于数组整体均值ave。就是找有没有非空真子集的均值和ave相同。
