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())
ans = []
d = {'A': A, 'B': B, 'C': C}
s = [input() for _ in range(N)]


def add_ans(s1, s2):
    d[s1] += 1
    d[s2] -= 1
    ans.append(s1)


for i in range(N):
    now = s[i]
    x = now[0]
    y = now[1]
    if d[x] == d[y] == 0:
        print('No')
        exit()
    elif d[x] == 0:
        add_ans(x, y)
    elif d[y] == 0:
        add_ans(y, x)
    elif i == N - 1:
        add_ans(x, y)
    elif x in s[i + 1]:
        add_ans(x, y)
    else:
        add_ans(y, x)

print("Yes")
for i in ans:
    print(i)
