HackerEarth The Perfect Road problem solution

In this HackerEarth The Perfect Road problem solution we have given that, there are N paths numbered from 1 to N, where each path connects the starting point S to the destination point X. The maximum speed limit is speed[i] for the ith path which can be used to reach the destination. Find the path to reach the destination as early as possible. If there are multiple paths from which you can choose, print Many Roads. Also, it is guaranteed that X will always be greater than S.
