Problem Statement

We have a connected undirected graph with $N$ vertices numbered $1$ to $N$ and $M$ edges numbered $1$ to $M$. Edge $i$ connects vertex $U_i$ and vertex $V_i$, and has an integer weight of $W_i$. For $1\\leq s,t \\leq N,\\ s\\neq t$, let us define $d(s,t)$ as follows.

• For every path connecting vertex $s$ and vertex $t$, consider the maximum weight of an edge along that path. $d(s,t)$ is the minimum value of this weight.

Answer $Q$ queries. The $j$-th query is as follows.

• You are given $A_j,S_j,T_j$. By what value will $d(S_j,T_j)$ increase when the weight of edge $A_j$ is increased by $1$?

Note that each query does not actually change the weight of the edge.

Constraints

• $2\\leq N \\leq 2\\times 10^5$
• $N-1\\leq M \\leq 2\\times 10^5$
• $1 \\leq U_i,V_i \\leq N$
• $U_i \\neq V_i$
• $1 \\leq W_i \\leq M$
• The given graph is connected.
• $1\\leq Q \\leq 2\\times 10^5$
• $1 \\leq A_j \\leq M$
• $1 \\leq S_j,T_j \\leq N$
• $S_j\\neq T_j$
• All values in the input are integers.

Input

The input is given from Standard Input in the following format:

$N$ $M$ $U_1$ $V_1$ $W_1$ $\\vdots$ $U_M$ $V_M$ $W_M$ $Q$ $A_1$ $S_1$ $T_1$ $\\vdots$ $A_Q$ $S_Q$ $T_Q$

Output

Print $Q$ lines. The $j$-th line $(1\\leq j \\leq Q)$ should contain the answer to the $j$-th query.

The above figure shows the edge numbers in black and the edge weights in blue.

Let us explain the first through sixth queries.

First, consider $d(4,6)$ in the given graph. The maximum weight of an edge along the path $4 \\rightarrow 1 \\rightarrow 2 \\rightarrow 6$ is $5$, which is the minimum over all paths connecting vertex $4$ and vertex $6$, so $d(4,6)=5$.

Next, consider the increment of $d(4,6)$ when the weight of edge $x\\ (1 \\leq x \\leq 6)$ increases by $1$. When $x=6$, we have $d(4,6)=6$, and the increment is $1$. On the other hand, when $x \\neq 6$, we have $d(4,6)=5$, and the increment is $0$. For instance, when $x=3$, the maximum weight of an edge along the path $4 \\rightarrow 1 \\rightarrow 2 \\rightarrow 6$ is $6$, but the maximum weight of an edge along the path $4 \\rightarrow 3 \\rightarrow 1 \\rightarrow 2 \\rightarrow 6$ is $5$, so $d(4,6)$ is still $5$.
