Dynamic Programming Approach for Finding Smaller Number Substrings
This soluiton addresses the challenge of counting reversible substrings where the reversed version would create a numerically smaller value.
DP Strategy
The dynamic programming approach builds solutions incrementally by comparing substring pairs:
For substrings of length 2, directly compare characters
For longer substrings, use previously comp ...

Detecting Overlapping Substrings in Python
Detecting overlapping substrings between two strings is a common task in various programming scenarios, such as text analysis, data preprocessing, and pattern matching. Python offers several srtaightforward approaches to achieve this.
A substring is considered overlapping if it appears contiguously in both strings. For instance, in "hello ...
