You are given two arrays of integers a and b. For each element of the second arraybj you should find the number of elements in array a that are less than or equal to the value bj. Input The first line contains two integers n, m (1 ≤ n, m ≤ 2·105) — t…
这次比上次多A了一道,但做得太慢,rating还是降了. Problem A Choose Two Numbers 题意:给出两个集合A,B,从A,B中分别选出元素a,b使得a+b既不属于集合A,又不属于集合B 数据范围:1<=集合A,B的大小<=100 1<=a,b<=200 我的做法是直接模拟就好了,复杂度:O(nm(n+m)) 题解的做法是分别取集合A,集合B中的最大值a,b就可以了,显然此时的a+b既不属于A,也不属于B #include <iostream>…
