题 Description The cows don't use actual bowling balls when they go bowling. They each take a number (in the range 0..99), though, and line up in a standard bowling-pin-like triangle like this: 7 3 8 8 1 0 2 7 4 4 4 5 2 6 5 Then the other cows travers…

题意:给2个数字序列 a 和 b ,问按从小到达排序后,a中的哪些子串与b的名次匹配. a 的长度 N≤100,000,b的长度 M≤25,000,数字的大小 K≤25. 解法:[思考]1.X 暴力.枚举 a 中的子串,选出来排序后比对名次.O(n* m log m *m)=O(n*m^2*log m). 2.X 暴力+树状数组优化.枚举 a 中的子串,选出来后比较前缀名次(P.S.这种转化常出现,比如:[洛谷 p3368]模板-树状数组 2(数据结构) 就是将个体转化为前缀.),看…
