题意: n个数字 下面n个数字表示数列 2个操作 1 [u, v]  k  add [u,v ]区间 (u点要计算)每隔k个位置,该数字+add 2 pos 询问 pos下标的值(下标从1开始) 思路: 因为k很小, 可以直接存 k[11] 注意查询时, 先找到 pos 所在的 叶子节点 再向上 添加 对应k位置的值 #include<iostream> #include<stdio.h> #include<algorithm> #include<string&g…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1698 区间更新重点在于懒惰标记. 当你更新的区间就是整个区间的时候,直接sum[rt] = c*(r-l+1);col[rt] = c:后面的子区间就不管了,当你下次更新某一个区间的时候,把col[rt]从顶往下推(也没有推到底),推到合适的位置,刚好这个位置是我要更新的区间的子区间(可能被横跨了)就停下来. 在这里感谢网上的大牛,感谢杰哥,彬哥.我才能AC. Just a Hook Time Li…
