For the daily milking, Farmer John's N cows (1 ≤ N ≤ 50,000) always line up in the same order. One day Farmer John decides to organize a game of Ultimate Frisbee with some of the cows. To keep things simple, he will take a contiguous range of cows fr…

题目传送门//res tp hdu 目的 对长度为n的区间,给定q个子区间,求一x,使得区间内所有元素与x的差的绝对值之和最小. 多测. n 1e5 q 1e5 ai [1,1e9] (i∈[1,n]); 数据结构 划分树 tip 该划分树维护的cnt并非元素所在区间内,该元素之前进入左子树的元素个数,而是整个区间内,该元素之前进入左子树的元素个数. #include<iostream> #include<cstdio> #include<cstring> #inclu…

平衡数的定义是指,以某位作为支点,此位的左面(数字 * 距离)之和 与右边相等,距离是指某位到支点的距离; 题意:求区间内满足平衡数的数量 : 分析:很好这又是常见的数位dp , 不过不同的是我们这次需要枚举是哪个位置是平衡点 , 一开始我是想说搜索到最后以为 ,然后得到这个数的位数 ,在判断平衡位置 , 想到这样的话 , 这就说明了我对数位dp 还是不太熟悉的 ,因为这样的话dfs() 里面的sum , emmm是找不到状态的 : 正解: 依然是枚举平衡点的位置  ,这个思路没有问题 , 但是…

题目描述:区间染色问题,统计给定区间内有多少种颜色? 线段树模板的核心是对标记的处理 可以记下沿途经过的标记,到达目的节点之后一块算,也可以更新的时候直接更新到每一个节点 Lazy操作减少修改的次数(在查询或者修改的过程中才更新标记对节点val值的影响,每次更新val值只更新到当前要查询或者修改的节点,最底层的标记以下的节点的val值应该是没有被更新过) Pushdown向下传递标记和修改子节点的val值, Pushup修改递归访问的节点的val值(更新父节点的val值) 大区间和小区间的先后修…
