Bob has a connected undirected edge-weighted graph with vertices and edges. There are no self-loops in this graph, but there can be multiple edges between some pairs of vertices.

Alice told Bob the following about this graph:

- The edge weights are
**distinct**integers from the range . In other words, they form some permutation of integers from to . - The weight of the -th edge is from the range for each from to .
- The edges with indices (the first edges in the input) form a
**minimum**spanning tree of this graph.

Bob wants to know if it is possible. Determine if there exist such assignments of edge weights for which these conditions hold and if yes, find any of them.

#### Input Format

The first line contains a single integer (), the number of test cases. The description of test cases follows.

The first line of each test case contains two integers and (), the number of vertices and the number of edges, respectively.

The -th of the following lines contains four integers , , , (, ), indicating that there is an edge connecting vertices , , and that its weight should be in range .

It's guaranteed that for each test case, edges with indices form a spanning tree of the given graph.

It's guaranteed the sum of over all test cases doesn't exceed .

#### Output Format

For each test case, if an array of edge weights that satisfy the conditions doesn't exist, output `NO`

in the first line.

Otherwise, in the first line, output `YES`

. In the second line output integers (, all are **distinct**), the edge weights (where is the weight assigned to the -th edge in the input).

If there are multiple answers, output any of them.
