Java
Write a Java to Implement Prim's and DIJKSTRA's algorithm for Single Source Shortest Path Problem with BINARY Heaps. The running time should be O(ElogV)
Your program should read data from file (see samples below) and output a single number = sum of lengths of the shortest paths from node 0 to each node.
INPUT FORMAT: The first line of each file below contains the number of vertices and the number of edges in the graph (in the format "n=XXXX m=XXXXX"). The rest of the file is organized as follows:
each vertex i appears on a line by itself, followed by a line for each neighbor j>i of i (containing j and the length of edge (i,j)). Each list of neighbors is ended by an empty line. Vertices i which do not have neighbors with an index greater than i are not represented.
NOTE: Vertices are indexed from 0 to n-1.
NOTE: each edge is mentioned only once with its smaller number endpoint
SAMPLE INPUT:
1. first input
2. second input
the length of the shortest path tree should be 10721073 and 625349 respectively.
Program should give output in 3-10 seconds for the first input and less than 1 second for the second.
