Write a program that reads a weighted graph and an initial vertex.
The program must print on the screen the minimum paths obtained by Dijkstra's algorithm.

Input: Receives n, m and s; n is the total number of vertices, m the total number of arcs and s is the initial vertex.
Next, m lines, each line with a trio of integers, corresponding to the beginning and end of the arc, followed by the weight of the arc.
(Vertices are identified from 0 to n-1.)

Output: Prints the shortest paths obtained by Dijkstra's algorithm.

Exemple:

Input:

5 10 0
0 1 10
0 4 5
1 2 1
1 4 2
2 3 4
3 2 6
3 0 7
4 1 3
4 2 9
4 3 2

Output:

[0, 8, 9, 7, 5]
[-1, 4, 1, 4, 0]
