Problem: There is a game that involves three variables, denoted A, B, and C.

As the game progresses, there will be N events where you are asked to make a choice. Each of these choices is represented by a string s_i. If s_i is `AB`, you must add 1 to A or B then subtract 1 from the other; if s_i is `AC`, you must add 1 to A or C then subtract 1 from the other; if s_i is `BC`, you must add 1 to B or C then subtract 1 from the other.

After each choice, none of A, B, and C should be negative.

Determine whether it is possible to make N choices under this condition. If it is possible, also give one such way to make the choices.

Constraints

* 1 \leq N \leq 10^5
* 0 \leq A,B,C \leq 10^9
* N, A, B, C are integers.
* s_i is `AB`, `AC`, or `BC`.

Input

Input is given from Standard Input in the following format:


N A B C
s_1
s_2
:
s_N


Output

If it is possible to make N choices under the condition, print `Yes`; otherwise, print `No`.

Also, in the former case, show one such way to make the choices in the subsequent N lines. The (i+1)-th line should contain the name of the variable (`A`, `B`, or `C`) to which you add 1 in the i-th choice.

Solution (in PYTHON3):

Solution:
N, A, B, C = map(int, input().split())
Ss = [input() for _ in range(N)]

ans = []
arr = {}
arr['A'] = A
arr['B'] = B
arr['C'] = C
for i, s in enumerate(Ss):
    v1 = s[0]
    v2 = s[1]
    if arr[v1] == arr[v2] == 0:
        print('No')
        exit()
    if i < N-1 and arr[v1] == arr[v2] == 1:
        if s == Ss[i+1]:
            ans.append(v1)
            arr[v1] += 1
            arr[v2] -= 1
        elif v1 in Ss[i+1]:
            ans.append(v1)
            arr[v1] += 1
            arr[v2] -= 1
        else:
            ans.append(v2)
            arr[v1] -= 1
            arr[v2] += 1
    elif arr[v1] < arr[v2]:
        ans.append(v1)
        arr[v1] += 1
        arr[v2] -= 1
    else:
        ans.append(v2)
