Given an array of 2n integers, your task is to group these integers into n pairs of integer, say (a1, b1), (a2, b2), ..., (an, bn) which makes sum of min(ai, bi) for all i from 1 to n as large as possible. Example 1: Input: [1,4,3,2] Output: 4 Explan…

给定长度为 2n 的数组, 你的任务是将这些数分成 n 对, 例如 (a1, b1), (a2, b2), ..., (an, bn) ,使得从1 到 n 的 min(ai, bi) 总和最大. 示例 1: 输入: [1,4,3,2] 输出: 4 解释: n 等于 2, 最大总和为 4 = min(1, 2) + min(3, 4). 提示: n 是正整数,范围在 [1, 10000]. 数组中的元素范围在 [-10000, 10000]. class Solution { public: in…

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…

You are given an integer array sorted in ascending order (may contain duplicates), you need to split them into several subsequences, where each subsequences consist of at least 3 consecutive integers. Return whether you can make such a split. Example…

原题: Given an array of 2n integers, your task is to group these integers into n pairs of integer, say (a1, b1), (a2, b2), ..., (an, bn) which makes sum of min(ai, bi) for all i from 1 to n as large as possible. 解析: 数组分割1 给一组2n个整数,分割为n组,一组2个数,使min(a,b)…
