1. Question on Graphs \n Shortest Distance From Source to Destination Variant .\n - Used Dijkstra\'s Algorithm and completed the solution. But in the end I got to know from  the interviewer that she was expecting optimized solution using BFS.\n (Haven\'t got any hint from the interviewer)\n \n Depressed. Solved the question But Still couldn\'t qualify.\n
