Interesting Sequence(有趣的数列)[Special judge] 题目概述:是否存在一个长度为n的整数数列,其任意连续p项之和为正数而任意连续q项之和为负数? 方法:连续项a[i],a[i+1]...a[j]和的性质容易联想到以前n项和的方式表达,即s[j]-s[i],简洁明了. 由此发现只需求一个满足要求的s[0]~s[n]. 其中s[i+p]-s[i]>0,s[i]-s[i-q]<0.即s[i] 同理有s[i]>s[i-p],s[i+q]. 这是拓扑排序的雏形.…

UVA1406 - A Sequence of Numbers(树状数组) 题目链接 题目大意: 给定N个数字.给两种操作:C x: 把这N个数字都加上x. Q x:查询这N个数里面有多少个数字和2^x取且大于0.最后把每一个查询的结果求和作为答案. 解题思路: 查询与2^x取且为1,那么就意味这那个符合要求的数的第x位要是1. 可是这里还有所有加上x的操作,能够用一个变量来记录所有C操作的x的和.有这个加数的话,第x位为1的可能能够通过低位进位得到,所以这里开16个树状数组,第i个树状数组存放…
