Queries for the Array 题解 前言这场CF 是我赛后打的,vp 赛时没做出来,后来发现是有个地方理解错了,有一些细节没有考虑到。现在换了一种思路来写,感觉更清晰了。做法首先需要动态维护三个变量,cntcnt 和finishsortfinishsort 和unfinishsortunfinishsort。这三个变量分别表示当前数字的个数,已经排好序的最后一...

Bob is living in a city in which houses are arranged in N*M blocks The city is denoted by N strings having M characters such that '.' denotes house while '#' denotes forests. Bob has to pay a certain amount LCost, RCost, UCost, DCost to move 1 step accross left, right, up or...
If the range partially covers a block, iterate over all the values covered by the range and add directly to those array values, updating the information in the map/multiset accordingly. For each zero query, take a look at each block: ...
Codeforces Round #538 (Div. 2)F Please, another Queries on Array? (数论+线段树+状态压缩) 题目链接:http://codeforces.com/contest/1114 题目大意: 查询结构, 初始给定一个序列,支持两种操作, 一种是 在区间上每个数都乘上一个x, 一种是查询区间上每个数累乘后的结果的欧拉函数。 题目分析: 这道题...
All numbers in the input are integers. For each query to calculate the sum print an integer — the required sum modulo1000000007 (109 + 7). Input The first line contains two integersnandm(1 ≤ n, m ≤ 105), showing, how many numbers are in the array and the number ...

You have to process q queries to this array; each query is given as four numbers l, r, x and y, denoting that for every i such that l ≤ i ≤ r and ai = x you have to set ai equal to y. Print the array after all queries are processed....
You have to processqqueries to this array. Each query is represented by two numberspandk. Several operations are performed in each query; each operation changesptop + ap + k. There operations are applied untilpbecomes greater thann. The answer to the query is the number of performed...
