HDU 1711 Number Sequence (字符串匹配,KMP算法) Description Given two sequences of numbers : a1, a2, ...... , aN, and b1, b2, ...... , bM (1 <= M <= 10000, 1 <= N <= 1000000). Your task is to find a number K which make aK = b1, aK+1 = b2, ...... , aK+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…
