KMP algorithmWhat is the KMP algorithm?Ask a question first: Given the string A and B, satisfy B must be a substring, ask first B and a overlapping b[1] corresponding to the ordinal of a.As an example: a:ababcedabced,b:abcedSo the answer is obviously 3, that is, a[3] starts the first time with B.So it's easy to think of the Brute Force algorithm O (n*m), right?Obviously easy tle ...Here we introduce a simple string matching algorithm: KMP.An example:

The main effect of the topic: To the n edge, to make these edges into a triangle, ask what is the largest area? All sides must be used. Ideas: For triangles with known perimeter, we can get the equation of state by knowing that the length of the two edges can be used to eject the third edge: F[I][J][K] Represents the use of the front I edge, can be composed of a length of J and K two edges Initialize f[0][0][0] = true; F[I][J][K] = F[i-1][j-len[i]][k] | | F[i-1][j][k-len[i]]; If f[i][j][k
