Problem Statement
Squid loves painting vertices in graphs.
There is a simple undirected graph consisting of N vertices numbered 1 through N, and M edges.
Initially, all the vertices are painted in color 0. The i-th edge bidirectionally connects two vertices ai and bi. The length of every edge is 1.
Squid performed Q operations on this graph. In the i-th operation, he repaints all the vertices within a distance of di from vertex vi, in color ci.
Find the color of each vertex after the Q operations.
Constraints
- 1 ≤ N,M,Q ≤ 105
- 1 ≤ ai,bi,vi ≤ N
- ai ≠ bi
- 0 ≤ di ≤ 10
- 1 ≤ ci ≤105
- di and ci are all integers.
- There are no self-loops or multiple edges in the given graph.
Subtasks
- Subtask 1 (30%): 1 ≤ N,M,Q ≤ 2000
- Subtask 2 (70%): No other constraints
- Subtask 3 (0%): Sample Testcases

Initially, each vertex is painted in color 0.
In the first operation, vertices 5 and 6 are repainted in color 1.
In the second operation, vertices 1, 2, 3, 4 and 5 are repainted in color 2.
