CF954I Yet Another String Matching Problem ( FFT ) Description 给出两个字符串S和T 定义两个等长的字符串A和B之间的距离为: 每次操作可以选择两个字符c1和c2,将两个字符串中的所有c1替换为c2,这样将A和B变为相等的最小操作次数。 求S的每个长度为|T|的子串和T之间的距离。 n<=125000,保证S和T只含...

Educational Codeforces Round 40 I. Yet Another String Matching Problem,http://codeforces.com/contest/954/problem/I给你两个串s,p,求上一个串的长度为|p|的所有子串和p的差距是多少,两个串的差距就是每次把一个字符变成另一个字符的最小次数,字符最大到f很明显,
954I Yet Another String Matching Problem,传送门分析我们先考虑暴力如何计算对于S的子串SS,如果它有位置i使得SS[i]!=T[i]那么我们就将两个字符之间用并查集连边最后答案很明显就是并查集中所有边的个数于是我们可以发现对于S[i]!=T[j]衣服那个会在S的第i-j个子串连边我

[28, 29], and in [30] it was also possible to show a link to another class of constructions, namely the T T¯-deformation of [31, 32]. When the original σ-model has an interpretation in terms of string theory, it is natural to ask whether the deformed models have one too, i...
