In this article, I will explain What is Naive String Matching Algorithm and How Does it Work.
The Naive String Matching algorithm is a simple algorithm used to find all occurrences of a pattern string in a text string. It works by comparing the pattern string with all substrings of the text string, starting from the first character of the text string and moving one character at a time.
At each position in the text string, the algorithm compares the first character of the pattern string with the character at that position in the text string. If the characters match, the algorithm checks the subsequent characters in the pattern string against the subsequent characters in the text string. Further, if all characters match, the algorithm reports a match at that position. If there is a mismatch, the algorithm moves on to the next position in the text string and repeats the process.
The time complexity of the Naive String Matching algorithm is O(mn), where m is the length of the pattern string and n is the length of the text string. This makes the algorithm relatively slow for long text and pattern strings. However, the algorithm is easy to implement and can be used as a baseline for more advanced string matching algorithms.
