CodeChefOpen on judge ↗

You are given a directed graph with N nodes and M edges. The nodes are numbered from 1 to N. Each node has a value Ai associated with it. It is guaranteed that array A has all distinct elements. You need to find a walk on this graph such that if you write down the values written on each node of the walk in the order they are visited, the length of the Longest Increasing Subsequence of that sequen
