### Longest Increasing Subsequence

Today, I encountered an interesting **problem on LeetCode** that required
familiarity with the "Longest Increasing Subsequence" algorithm. Although my
initial solution, which involved something similar to Monotonic Stack, was
enough to pass the tests, I decided to explore the problem more deeply by
requesting this subsequence for each element of the array.

The wiki page for
**Longest Increasing Subsequence - wiki**
may provide a more complex explanation than
needed for the LeetCode problem, but it can serve as a foundation for tackling
more complex problems, which I used to solve.
