Shortest Route Codechef Problem

Hey @Ayush7614 @Amit366
I wish to work on **shortest route problem** from CodeChef Challenge .
**Problem Statement**
[https://www.codechef.com/JUNE21C/problems/SHROUTE](url)

I am interested to use **C++**
kindly assign this issue to me under LGM SOC '21

Start by reading the linked CodeChef SHROUTE problem statement and inspecting the repository's existing C++ solution organization to find the appropriate entry point. Done means adding a C++ solution for the shortest-route problem in the project's expected location and format, with any relevant sample or verification cases passing.
