Step 1: Set the distance of H as d(H) = 0 and set the distance of other node to be infinity.
Step 2: The cvurrent node is H. Check its neighbors A and B, Set d(A) = d(H) + d(A, H) = 2,
d(B) = d(H) + d(B, H) = 1. Set parent of both A and B to be H. Mark H as visited.
Step 3: Current node is B since d(B) =1 is the smallest of all unvisited nodes.
Check its neighbor C and update d(C) = d(B) + d(B, C) = 1 + 2 = 3,
set C's parent to be B. Mark B as visited.
Step 4: Current node is A since d(A) =2 is the ...
