A string and a pattern are given to you. You have to match the pattern and string without using regular expression.
Input: Test Case T. T no. of lines with the strings and patterns. E.g. 3 abcbbabc aba Includehelp aa GreenRedYellowRed GRYR Output: Print the character with their respectively representation.
T= 3 Input: String : abcbbabc Pattern: aba Output: a → abc b → bb Input: String : Includehelp Pattern: aa Output: Matching not possible. Input: String : GreenRedYellowRed Pattern: GRYR Output: G → Green R → Red Y → Yellow
Match a string with a pattern is a problem of combination and we will solve this problem with the backtracking process.
To solve this problem, we will follow this algorithm,
