Graph Coloring
Description
You are given an undirected graph without self-loops or multiple edges which consists of $n$ vertices and $m$ edges. Also you are given three integers $n_1$, $n_2$ and $n_3$.
Can you label each vertex with one of three numbers 1, 2 or 3 in such way, that:
- Each vertex should be labeled by exactly one number 1, 2 or 3;
- The total number of vertices with label 1 should be equal to $n_1$;
- The total number of vertices with label 2 should be equal to $n_2$;
- The total number of vertices with label 3 should be equal to $n_3$;
- $|col_u - col_v| = 1$ for each edge $(u, v)$, where $col_x$ is the label of vertex $x$.
If there are multiple valid labelings, print any of them.
The first line contains two integers $n$ and $m$ ($1 \le n \le 5000$; $0 \le m \le 10^5$) — the number of vertices and edges in the graph.
The second line contains three integers $n_1$, $n_2$ and $n_3$ ($0 \le n_1, n_2, n_3 \le n$) — the number of labels 1, 2 and 3, respectively. It's guaranteed that $n_1 + n_2 + n_3 = n$.
Next $m$ lines contan description of edges: the $i$-th line contains two integers $u_i$, $v_i$ ($1 \le u_i, v_i \le n$; $u_i \neq v_i$) — the vertices the $i$-th edge connects. It's guaranteed that the graph doesn't contain self-loops or multiple edges.
If valid labeling exists then print "YES" (without quotes) in the first line. In the second line print string of length $n$ consisting of 1, 2 and 3. The $i$-th letter should be equal to the label of the $i$-th vertex.
If there is no valid labeling, print "NO" (without quotes).
Input
The first line contains two integers $n$ and $m$ ($1 \le n \le 5000$; $0 \le m \le 10^5$) — the number of vertices and edges in the graph.
The second line contains three integers $n_1$, $n_2$ and $n_3$ ($0 \le n_1, n_2, n_3 \le n$) — the number of labels 1, 2 and 3, respectively. It's guaranteed that $n_1 + n_2 + n_3 = n$.
Next $m$ lines contan description of edges: the $i$-th line contains two integers $u_i$, $v_i$ ($1 \le u_i, v_i \le n$; $u_i \neq v_i$) — the vertices the $i$-th edge connects. It's guaranteed that the graph doesn't contain self-loops or multiple edges.
Output
If valid labeling exists then print "YES" (without quotes) in the first line. In the second line print string of length $n$ consisting of 1, 2 and 3. The $i$-th letter should be equal to the label of the $i$-th vertex.
If there is no valid labeling, print "NO" (without quotes).
