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())

nums = {"A": a, "B": b, "C": c}

s = []
for i in range(n):
    line = input()
    s.append(line)

def add(a, b):
    nums[a] += 1
    nums[b] -= 1
    ans.append(a)

flag = True

ans = []

for i in range(n):
    a = s[i][0]
    b = s[i][1]

    if nums[a] == 0 and nums[b] == 0:
        print("No")
        flag = False
        break

    if nums[a] == 0:
        add(a, b)
        
    elif nums[b] == 0:
        add(b, a)
        
    else:
        if i != n - 1:
            na = s[i + 1][0]
            nb = s[i + 1][1]

            if (a == na or a == nb):
                add(a, b)

            else:
                add(b, a)

        else:
            add(a, b)
if flag:
    print("Yes")

    for i in ans:
        print(i)
