I was coding in C++14 and there seems to be something out of order in the code for it is not giving me the right answer in Codechef IDE and on DevCpp it is not even compiling! I believe the code is logically sound and there are only semantic errors in it. Let the node at which we are starting be called the initial node. Let the distance of node Y be the distance from the initial node to Y. Dijkstra's algorithm will initially start with infinite distances and will try to improve them step by step. 1. Mark all nodes unvisited. Create a set of all the unvisited nodes called the unvisited set. 2. Assign to every node a tentative distance value: set it to zero for our initial node and to infinity for all oth… WebMar 20, 2016 · Below is algorithm based on set data structure. 1) Initialize distances of all vertices as infinite. 2) Create an empty set.
