Contributor guide

Research direction
Implement the algorithm to find the next lexicographic permutation of digits. You can study the 'next permutation' pattern (e.g., from C++ std::next permutation or algorithm steps). Write a function that takes an integer, converts to string/vector of digits, applies the algorithm, and returns the next larger number as integer.
