Introduction to Longest Common Substring
Explore the longest common substring pattern in dynamic programming. Understand how to identify consecutive matching substrings in two strings, grasp the difference between substring and subsequence, and apply these concepts to solve string matching problems commonly seen in coding interviews.
We'll cover the following...
Overview
In this pattern, we will be discussing 12 problems related to this pattern. The following diagram shows an overview of this pattern.
The Longest Common Substring (LCS) is defined as the longest substring that is common in the given two strings. In the longest common substring problems, the elements of a substring must be consecutive as in the original strings. A slight variation of LCS is the Longest Common Subsequence, in which the elements of the substrings are not necessarily required to occupy consecutive positions within the original strings. In either case, the indices of the common ...
Mathematically, it can be written as:
Given two strings and ...
