If the required partition exists, print groups of three. Print each group as values of the elements it contains. You should print values in increasing order. Separate the groups and integers in groups by whitespaces. If there are multiple solutions, you can print any of them. If there is no solution, print -1.

The first line of input contains two space-separated integers n and m (2 ≀ n ≀ 2Β·105, n - 1 ≀ m ≀ 2Β·105), the number of vertices and edges in the graph. The following m lines contain three space-separated integers ai, bi and ci (1 ≀ ai, bi ≀ n, ai ≠ bi, 1 ≀ ci ≀ 104), which means that there is an undirected edge from a...

Output m lines, each containing one integer di, which should be 0 if the direction of the i-th edge is ai → bi (the flow goes from vertex ai to vertex bi) and should be 1 otherwise. The edges are numbered from 1 to m in the order they are given in the input. If there are several solutions you can print any of them.

There is a straight snowy road, divided into n blocks. The blocks are numbered from 1 to n from left to right. If one moves from the i-th block to the (i + 1)-th block, he will leave a right footprint on the i-th block. Similarly, if one moves from the i-th block to the (i - 1)-th block, he will leave a left footprint ...

The first line of the input contains integer n (3 ≀ n ≀ 1000). The second line contains the description of the road β€” the string that consists of n characters. Each character will be either "." (a block without footprint), or "L" (a block with a left footprint), "R" (a block with a right footprint). It's guaranteed tha...
