Problem:
Score : 700 points

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.

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.

Partial Score

200 points will be awarded for passing the testset satisfying 1 ≤ N,M,Q ≤ 2{,}000.

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.

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.

Solution in Perl (v5.18.2) (judge verdict: Wrong Answer)

my @data =<STDIN>;

my @num = split(/ /, $data[0]);
my $pn = $num[0];
my $en = $num[1];

my @result;
for(1..$pn) { push(@result, 0); }

	my @ele = split(/ /, $data[$_]);
	push(@edge, "$ele[0],$ele[1]");
	push(@edge, "$ele[1],$ele[0]");

my $cn = $data[$en+1];

for(1..$cn) {
	my @ele = split(/ /, $data[$en+1+$_]);
	my $sp = $ele[0];
	my $d = $ele[1];
	my $c = $ele[2];
