C# Program for Naive algorithm for Pattern Searching
Given a text txt[0..n-1] and a pattern pat[0..m-1], write a function search(char pat, char txt) that prints all occurrences of pat in txt. You may assume that n > m.
Input: txt = "THIS IS A TEST TEXT" pat = "TEST" Output: Pattern found at index 10 Input: txt = "AABAACAADAABAABA" pat = "AABA" Output: Pattern found at index 0 Pattern found at index 9 Pattern found at index 12
Pattern searching is an important problem in computer science. When we do search for a string in notepad/word file or browser or database, pattern searching algorithms are used to show the search results.
Pattern found at index 0 Pattern found at index 9 Pattern found at index 13
Time Complexity: O(M * (N – M + 1)), where M and N represents the length of the given strings.
Auxiliary Space: O(1), no extra space is required, so it is a constant.
