The brute force solution will go back to the pointer i as stupidly as the above example, and the KMP algorithm will be clever: Because the KMP algorithm knows that the character a before the character b is matched, it is only necessary to compare whether the character b is...
In order to escape from such boring job, the innovative little cat works out an easy but fantastic algorithm: Step1. Connect the father's name and the mother's name, to a new string S. Step2. Find a proper prefix-suffix string of S (which is not only the prefix, but also the ...

Recently I have learned KMP. I am trying to solve the problem for a while but cant understand, What should be my first approach? Can anyone explain me step by step. Any hint would be greatly appreciated. Problem Link:http://lightoj.com/volume_showproblem.php?problem=1268Those Who haven'...

Given two strings a and b we define a*b to be their concatenation. For example, if a = "abc" and b = "def" then a*b = "abcdef". If we think of concatenation as multiplication, exponentiation by a non-negative integer is defined in the normal way: a^0 = "" (the empty string...
KMP is the abbr. of Knuth-Morris-Pratt, one of the authors of this algorithm. The other two are Donald Knuth and Vaughan Pratt. They solve the above problem in a more efficient way. Let's explain it using an example. The last example is not good enough for explain this algorithm, let...
