给出了一个序列,你需要处理如下两种询问。 "C a b c"表示给[a, b]区间中的值全部增加c (-10000 ≤ c ≤ 10000)。 "Q a b" 询问[a, b]区间中所有值的和。 Input 第一行包含两个整数N, Q。1 ≤ N,Q ≤ 100000. 第二行包含n个整数,表示初始的序列A (-1000000000 ≤ Ai ≤ 1000000000)。
You haveNintegers,A1,A2, ... ,AN. You need to deal with two kinds of operations. One type of operation is to add some given number to each number in a given interval. The other is to ask for the sum of numbers in a given interval. Input The first line contains two numbersNandQ....
传送门 题目大意就是给出两个操作: C:将一个区间里的都数增加c ,Q:查询区间(a,b)内的和。多次操作,很明显(原谅我用了这么罪恶的词)要用线段树来维护。 线段树的区间修改和点修改相比多了一个add数组,add数组的作用是在进行区间更新的时候不必将和该区间有关的所有线段都更新,某个线段的add数组的含义是:该...
