Hi there!!
I do not know hoe to implement the Dijksta so could not submit to 144D of codeforces round 103.
After that I took the help of somersault's code.
But my implemtation gives me a compilation error.Note that I have not written the full code.I just wanted to implement Dijkstra.Please help me.
