二维的树状数组,,, 记得矩阵的求和运算要想好在写.... 代码如下: #include <cstdio> #include <cstdlib> #include <cmath> #include <cstring> #include <cstdlib> #include <stack> #include <queue> #include <vector> #include <algorithm>…
树状数组,开始的时候wa了,后来看看,原来是概率论没学好,以为求(L,B) - (R,T) 矩阵内的和只要用sum(R+1,T+1) - sum(L,B) 就行了,.傻x了.. 必须 sum(R,T) - sum(L,T) - sum(R,B) + sum(L,B) ;  (R,T 已经自加1)   诫之. 代码: #include <iostream> #include <cstdio> #include <cstring> #include <cmath>…
树状数组支持两种操作: Add(x, d)操作:   让a[x]增加d. Query(L,R): 计算 a[L]+a[L+1]……a[R]. 当要频繁的对数组元素进行修改,同时又要频繁的查询数组内任一区间元素之和的时候,可以考虑使用树状数组. 通常对一维数组最直接的算法可以在O(1)时间内完成一次修改,但是需要O(n)时间来进行一次查询.而树状数组的修改和查询均可在O(log(n))的时间内完成. 在二维情况下:数组A[][]的树状数组定义为: C[x][y] = ∑ a[i][j], 其中, …

树状数组,学长很早之前讲过,最近才重视起来,enmmmm... 树状数组(Binary Indexed Tree(B.I.T), Fenwick Tree)是一个查询和修改复杂度都为log(n)的数据结构.主要用于查询任意两位之间的所有元素之和,但是每次只能修改一个元素的值:经过简单修改可以在log(n)的复杂度下进行范围修改,但是这时只能查询其中一个元素的值(如果加入多个辅助数组则可以实现区间修改与区间查询). 树状数组和线段树很像,但能用树状数组解决的问题,基本上都能用线段树解决,而线段树能…
