伸展数最基本操作的模板,区间求和,区间更新.为了方便理解,特定附上一自己搞的搓图 这是样例中的数据输入后建成的树,其中的1,2是加入的边界顶点,数字代表节点编号,我们如果要对一段区间[l, r]进行操作,只需要把第l-1位的数旋转到0节点下面,把r+1位的数旋转到当前的root下面,就如上图所示,那么椭圆里表示的就是区间[l, r]. 附上注释代码.指针版本的比静态数组的快1s多.. /* ********************************************** Author…

题目地址http://poj.org/problem?id=3468 题目大意很简单,有两个操作,一个 Q a, b 查询区间[a, b]的和 C a, b, c让区间[a, b] 的每一个数+c 第一次线段树的延时标记,花了好大的功夫才写好==! 很容易看出来使用使用线段树记录区间的和,但是难点在于每次修改的是一个区间而不是一个点 所以采用的方法就是每次做修改操作时,只将区间［a,b］的标记+c,而不是真正意义上的将区间[a, b] 的每一个值+c. 而当我们做查询操作时,就只需要将区间[a,…
