Python Question 62:
Substring in a String and Reverse
Video 161: In this video, we'll find the Existence of a Substring in a String and Its Reverse.
We are given a string s, and asked to find any substring of length 2 which is also present in the reverse of s.
Return true if such a substring exists, and false otherwise.
In this video, we delve into the intriguing problem of finding mirror substring pairs within a given string. We explore three distinct approaches to tackle this challenge, each offering its unique perspective and efficiency.
*** Approach 1: Matching Substrings ***
In the first approach, we traverse through the string, identifying substrings of length 2 and checking if they exist in the reversed version of the string. This method focuses on finding all matching substrings and returns True if any are found.
*** Approach 2: First Occurrence Search ***
The second approach aims to optimize the search process by halting as soon as a matching substring is encountered. This approach prioritizes speed by returning True immediately after finding the first mirror substring pair.
*** Approach 3: Real-time Comparison ***
Our third approach adopts a real-time comparison strategy, where we maintain a set to store encountered substring pairs. We iterate through the string, checking for mirror substring pairs and returning True if any are found.
For a comprehensive understanding and practical demonstration, be sure to watch the entire video. Happy coding!
