备忘. 差分数组: 区间更新查询有很多方法,线段树.树状数组等都可以.如果为离线查询,就可以考虑使用差分数组. 假设对于区间[l,r]的每个数都加1,我们用一个数组a来记录,a[l]+=1;a[r+1]-=1; 然后使用一个数组ans来记录数组a的前缀和,ans[i]=ans[i-1]+a[i];ans保存的就是所有更新操作完成后每个数对应的值. 原理很好理解,树状数组也有这种思想. 差分数组代码可比线段树短了相当多,记住这个还是很好的. Color the ball Time Limit: 9…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1556 题目意思:有 n 个气球从左到右排成一排,编号依次为1,2,3,...,n.给出 n 对 a, b,表示编号为 a ~b 的气球被涂过一次色.n 次之后,问所有气球被上色的次数分别是多少. 典型的树状数组题!这种是:每次修改一个区间,问的是最后每个点被修改的次数.要注意update() 函数对 a 处理 的时候,向上修改的过程中把不必要的区间都加了一遍.例如对a = 2时,update修改了c…
