给定一个初始元素全部为 0,大小为 m*n 的矩阵 M 以及在 M 上的一系列更新操作. 操作用二维数组表示,其中的每个操作用一个含有两个正整数 a 和 b 的数组表示,含义是将所有符合 0 <= i < a 以及 0 <= j < b 的元素 M[i][j] 的值都增加 1. 在执行给定的一系列操作后,你需要返回矩阵中含有最大整数的元素个数. 示例 1: 输入: m = 3, n = 3 operations = [[2,2],[3,3]] 输出: 4 解释: 初始状态, M =…
problem 598. Range Addition II 题意: 第一感觉就是最小的行和列的乘积即是最后结果. class Solution { public: int maxCount(int m, int n, vector<vector<int>>& ops) { for(auto op : ops) { m = min(m, op[]); n = min(n, op[]); } return m*n; } }; 参考 1. Leetcode_easy_598.…
