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:

itos = ["A", "B", "C"]

def swap(ABC, f, t):
    ABC[f] -= 1
    ABC[t] += 1
    return itos[t]


def main():
    N, A, B, C = map(int, input().split())
    S = [input() for i in range(N)]
    ABC = [A, B, C]
    StoP = {"AB": (0, 1), "BC": (1, 2), "AC": (0, 2)}
    itos = ["A", "B", "C"]
    L = []
    for i in range(N):
        x, y = StoP[S[i]]

        if ABC[x] == 0 and ABC[y] == 0:
            print("No")
            return
        if ABC[x] == 1 and ABC[y] == 1 and i < N - 1 and S[i] != S[i+1]:
            x2, y2 = StoP[S[i+1]]
            if x in [x2, y2]:
                L.append(swap(ABC, y, x))
            else:
                L.append(swap(ABC, x, y))
        elif ABC[x] < ABC[y]:
