Longest Increasing Subsequences

CodeChefOpen on judge ↗

Chef recently learned about the classic Longest Increasing Subsequence problem. However, Chef found out that while the length of the longest increasing subsequence is unique, the longest increasing subsequence itself is not necessarily unique; for example, in the array [1, 3, 2, 4], there are two longest increasing subsequences: [1, 3, 4] and [1, 2, 4].
