B+树、B*树谈到R 树，这次，咱们来讲另外两种树：Tire树与后缀树。
Or -1 if [subseq] is not a subsequence of [seq]. The time complexity of the algorithm is O(n*m), where n, m = len(seq), len(subseq). >>>index('12', '0112') [2] >>>index([1,2], [011212]) [2, 4] >>>index('13', '0112') -1 ''' i, n, m = -1, len(seq...

The method has overall time complexity O(m + n), where m and n are the number of characters in pattern string (P) and text string (T) respectively. The essence of KMP algorithm has been extended to generalize the pattern matching problem for two dimensio...

We are now ready to see the full algorithm and how it uses the prefix table.Notice how we use the Prefix Table only when a mismatch occurs and if "j" which in this case points to pat is greater than 0. The runtime complexity of this new version in the worst case will be O...

Hello everyone , I am trying to read thistop coder tutorialand understood the working of KMP algorithm completely. I have found this problem at the end of this post. A typical problem seen quite often is: given a string find its shortest substring, such that the concatenation of one or mo...
