Pattern: 3 QS

You are given an undirected connected graph with N nodes and M edges. The nodes are numbered from 0 to N-1.

Each edge connects two nodes and normally has a weight of 1.

You are also given:

• A source node S
• A special node V

Your task is to find the minimum distance from the source node S to every other node.

Special Rule

Whenever a path reaches the special node V, the cost of reaching V becomes 0.

Moreover, after reaching V, every node that is directly connected to V can also be reached with zero additional cost.

In other words, the special node acts as a zero-cost node: moving to V costs 0, and moving from V to any of its adjacent nodes also costs 0.

Return an array dist where dist[i] represents the minimum cost required to reach node i from the source node S.

Input Format

• The first line contains an integer N, the number of nodes.
• The second line contains an integer M, the number of edges.
• The next M lines contain two integers u and v, representing an undirected edge between nodes u and v.
• The next line contains an integer S, the source node.
• The last line contains an integer V, the special node.

Output Format

Print N integers where the i-th integer represents the minimum distance from S to node i.

Example

0 1
1 2
2 3
3 4
1 3
2
0

Output

0 1 1 1 2

Explanation

The source node is 2 and the special node is 0.

The normal shortest distances from node 2 are:

• dist[2] = 0
• dist[1] = 1
• dist[3] = 1
• dist[0] = 2
• dist[4] = 2

Therefore, the resulting distance array is:

0 1 1 1 2
