Polycarpus has a string t, he wants to know the number of pairs of positions that define string t. Note that the way from the first position to the second in the pair must go down everywhere. Help him with this challenging tree-string problem! The first line contains integer n (2 ...

因为字符最多只有3∗1053∗105个,那么把字符拆成一个个点,构出一张新图,又因为题目中有限制,必须是一条从上往下的路径, 所以对于每个点都考虑以当前点为结尾的字符串是否与要求的相同,这个的话hashhash就可以了, 然后取出一段祖先区间就用倍增维护好了。 做法暴力,好写好想… 1 2 3 4 5 6 7 8 9 1...

stringtree-checklist A simple helper to get round the problem of checking returned collections. It's a common enough problem, particularly in testing remote and/or asynchronous systems, that you wish to assert that some collection of values are returned or supplied. Naive approaches such as collec...
