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())
A = [a, b, c]
D = {'AB': 0, 'BC': 1, 'AC': 2}
S = [input() for i in range(n)]
S.append('AB')
X = []
for i in range(n):
    x, y = D[S[i]], (D[S[i]] + 1) % 3
    if A[x] == 0 and A[y] == 0:
        print('No')
        exit()
    if A[x] < A[y]:
        A[x], A[y] = A[x] + 1, A[y] - 1
        X.append('ABC'[x])
    elif A[x] > A[y]:
        A[x], A[y] = A[x] - 1, A[y] + 1
        X.append('ABC'[y])
    else:
        x1, y1 = D[S[i + 1]], (D[S[i + 1]] + 1) % 3
        if x == y1:
            A[x], A[y] = A[x] + 1, A[y] - 1
            X.append('ABC'[x])
        else:
            A[x], A[y] = A[x] - 1, A[y] + 1
            X.append('ABC'[y])
print('Yes')
print(*X, sep='\n')
