题意:给你两串数字,问你第二串数字第一次出现在第一串数字的位置,没有输出-1: 解题思路:其是就是字符串匹配,就是这里是数字匹配,把char数组改成int型就可以了: 代码: #include<iostream> #include<algorithm> #include<cstdio> #include<cstring> #define M 10050 #define N 1005000 using namespace std; int next1[M];…

链接 HDU 1711 Number Sequence KMP 算法 我以自己理解写的,写的不对,不明白的地方海王子出来,一起共同学习: 字符串匹配 就是KMP,一般思想,用一个for循环找开头 如果开头一样进入第二个for循环:这样统计 直观 容易理解.但是时间复杂度比较长.所以就有KMP 这个算法了 KMP 大体思想因为在上一个方法之中,有的字符重复比较了,使得找到目标字符窜效率比较低, 比如 :目标串为: ① a b a b c 在 ② a…
