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 a_i and b_i. 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 d_i from vertex v_i, in color c_i.
Find the color of each vertex after the Q operations.
Input
Input is given from Standard Input in the following format:
N M
a_1 b_1
:
a_{M} b_{M}
Q
v_1 d_1 c_1
:
v_{Q} d_{Q} c_{Q}
Output
Print the answer in N lines.
In the i-th line, print the color of vertex i after the Q operations.
Constraints
- 1 ≤ N,M,Q ≤ 10^5
- 1 ≤ a_i,b_i,v_i ≤ N
- a_i ≠ b_i
- 0 ≤ d_i ≤ 10
- 1 ≤ c_i ≤10^5
- d_i and c_i are all integers.
- There are no self-loops or multiple edges in the given graph.

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.
