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
value of I must be greater than MAXID,That means the entire program ends,The while loop performs an operand of n (linear) time,Each character in the string can be accessed up to 2 times.The complexity of time must be O (n)Paste the code:# include using namespacestd;Const intmaxn=11000005*2;Chara[2*MAXN];intp[2*MAXN];intMain () {CharCh=getchar ();intt=0; a[0]='?';//for the sake of insurance a[0] and the last symbol cannot be the same while(Isalpha (ch)) {T++; a[2*t]=ch; a[2*t-1]='#'; CH=GetC

Second, to ensure code performance
Note scope:
Avoid global lookups: using global variables and functions is certainly more expensive than local, because it involves lookups on the scope chain.
