说实在的在比赛时看错了题意,一直对最后一段的描述不是很清楚.闲话少说: 题意:给一个主串,再一个副串,问主串中有多少个子串和副串的的规律相同,即相邻的相等大于小于,用过的就不能再用了. #include <stdio.h> #include <string.h> #include <stdlib.h> ],B[]; int find(int i,int m) { int j; ;j <= m - ;j ++) { ] && B[j] == B[j…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4749 题目大意:给一个原序列N,再给出一个序列M,问从N中一共可以找出多少个长度为m的序列,序列中的数的相对大小关系与序列M中相对大小关系相同.(序列之间不能重叠) 解题思路:从头开始以i为起点暴搜,不断找长度为m的序列,判断是否满足条件.若满足,跳到i+m之后继续搜,若不满足,向后移一位继续搜. 判断方法压缩数据比较相对大小. #include<cstdio> #include<cstri…

看大神代码,发现上交大神很棒的一个思路 题意: 在源数字串中找出尽量多的连续子串,要求子串任意两值的大小关系与目标串相同位置的值的大小关系相同.求源串能拿出的子串的最大数量. 关键词: RK-Hash 优点: O(k)时间完成匹配检查(关键在于他能O(1) 完成 所有 相同位 检查) 方法: 对于一个K值,用某个进制数来表示其位置. 比如 123121 中 的值 1 最后表示成 100101. 然后,对于目标串也RK-hash,对于某个值,只要比较这个数,就能知道是否相同位都相同了. 代码留恋:…
