Description

You are given an undirected graph without self-loops or multiple edges which consists of nn vertices and mm edges. Also you are given three integers n1n_1, n2n_2 and n3n_3.

Can you label each vertex with one of three numbers 1, 2 or 3 in such way, that:

  1. Each vertex should be labeled by exactly one number 1, 2 or 3;
  2. The total number of vertices with label 1 should be equal to n1n_1;
  3. The total number of vertices with label 2 should be equal to n2n_2;
  4. The total number of vertices with label 3 should be equal to n3n_3;
  5. colucolv=1|col_u - col_v| = 1 for each edge (u,v)(u, v), where colxcol_x is the label of vertex xx.

If there are multiple valid labelings, print any of them.

The first line contains two integers nn and mm (1n50001 \le n \le 5000; 0m1050 \le m \le 10^5) — the number of vertices and edges in the graph.

The second line contains three integers n1n_1, n2n_2 and n3n_3 (0n1,n2,n3n0 \le n_1, n_2, n_3 \le n) — the number of labels 1, 2 and 3, respectively. It's guaranteed that n1+n2+n3=nn_1 + n_2 + n_3 = n.

Next mm lines contan description of edges: the ii-th line contains two integers uiu_i, viv_i (1ui,vin1 \le u_i, v_i \le n; uiviu_i \neq v_i) — the vertices the ii-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 nn consisting of 1, 2 and 3. The ii-th letter should be equal to the label of the ii-th vertex.

If there is no valid labeling, print "NO" (without quotes).

Input

The first line contains two integers nn and mm (1n50001 \le n \le 5000; 0m1050 \le m \le 10^5) — the number of vertices and edges in the graph.

The second line contains three integers n1n_1, n2n_2 and n3n_3 (0n1,n2,n3n0 \le n_1, n_2, n_3 \le n) — the number of labels 1, 2 and 3, respectively. It's guaranteed that n1+n2+n3=nn_1 + n_2 + n_3 = n.

Next mm lines contan description of edges: the ii-th line contains two integers uiu_i, viv_i (1ui,vin1 \le u_i, v_i \le n; uiviu_i \neq v_i) — the vertices the ii-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 nn consisting of 1, 2 and 3. The ii-th letter should be equal to the label of the ii-th vertex.

If there is no valid labeling, print "NO" (without quotes).
