Unexplored:

1. Restore all the possible LISs in the O(n^2) DP solution.
2. There are other ways of implementing the solution and more problems on this: https://cp-algorithms.com/sequences/longest_increasing_subsequence.html
3. Check more on: https://usaco.guide/gold/lis?lang=cpp

Explored:

See codes with comments here. Currently we have two implementations- n^2 with DP and nlogn with binary search.
