Header file and namespace :: # Include Using namespace STD; Use the subscript type for traversal: String: The size_type type describes the type of the string type lower mark. So the method for traversing the string type is: For (string: size_type I

1. CharIndex1: CharIndex Syntax: CharIndex (expression1, expression2 [, start_location]) 2: an expression of the parameter expression1, which contains the sequence of characters to be searched. Expression1 is a string data expression. Expression2 is

　　Summary: This article discusses the time complexity of Related Algorithms for longest common substrings. Then, based on the suffix array, a time complexity O (N ^ 2 * logn) is proposed ), the space complexity is O (n. Although this algorithm is
