Description You are given two arrays of integers a and b. For each element of the second array bj you should find the number of elements in array athat are less than or equal to the value bj. Input The first line contains two integers n, m (1 ≤ n, m …

CF 600B 题目大意:给定n,m,数组a(n个数),数组b(m个数),对每一个数组b中的元素,求数组a中小于等于数组该元素的个数. 解题思路:对数组a进行排序,然后对每一个元素b[i],在数组a中进行二分查找第一个大于b[i]的位置即为结果 /* CF 600B Queries about less or equal elements --- 二分查找 */ #include <cstdio> #include <algorithm> using namespace std;…

首先说明一下MEX,设S是自然数集合N的一个子集,那么S的MEX则为min(N\S),即不包含于S的最小自然数. 题目大意是存在一个空集S,提供n组输入(n<10^5),每组输入对应下面的一个指令(1 ≤ l ≤ r ≤ 10^18): 1.将集合[l, r]包含到S中. 2.将集合[l, r]从S中移除. 3.将[l, r]与S的交集从S中移除,并将S\[l, r]加入到S中.(即从S移除所有同时出现在[l, r]与S中的元素,添加所有只出现于[l, r]但不在S中出现的元素) 每个指令都需要…
