由于简单模式匹配算法在一次字符比较失败后,简单的把模式串位置向前移动一个字符位置,这样就丢掉了前面字符匹配中得到的信息,效率差。所以就需要一种无回溯的算法来提高效率,这里使用KMP(Knuth-Morris-Pratt)算法。模式串前面的连续片断部分称“前缀模式”,前缀模式在模式串后部重复出现的情况可以用来避免重复进行已经做过的检查,这是KMP算法中的一个重要概念。-as simple pattern-matching algorithm to compare a character failure, a simple model put forward position Series mobile location of a character, would be lost in front of characters matching the information inefficiently. There is a need for a non-backtracking algorithms to improve efficiency, the use of KMP here (Knuth-Morris-Pratt) algorithm. Model Series in front of a row clips part said "prefix model," prefix string pattern in the pattern of recurring back can be used to avoid duplication of inspection has been done, KMP algorithm is an important concept.

零件切割问题:
给定一块宽度为W的矩形板,矩形板的高度不受限制。现需要从板上分别切割出n个高度为hi,宽度为wi的矩形零件。切割的规则是零件的高度方向与矩形板的高度方向保持一致。问如何切割使得所使用的矩形板的高度h最小?
任给一个输入实例,能输出切割所需要的实际高度并能用图形演示切割的过程-cutting parts : a given width of the rectangular plate W, the height of rectangular plate unrestricted. Need from the board is cutting out respectively n height of the hi, wi width of the rectangular parts. Cutting parts to the rules of the height of the rectangular plate with a high degree of consistent direction. Asked how cutting makes use of the rectangular plate height h minimum? As an input for example, will cut output by the needs of the high and can be used graphic demonstration of the cutting proce
