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())
s = [input() for _ in range(n)]

d = {'A':a,'B':b,'C':c}

ans = ['Yes']

for i in range(n):
    if d[s[i][0]] == 0 and d[s[i][1]] == 0:
        print('No')
        exit()
    if d[s[i][0]] == 1 and d[s[i][1]] == 1 and n-i > 1:
        d[s[i][0]] = 2
        d[s[i][1]] = 0
        if d[s[i+1][0]] == 0 and d[s[i+1][1]] ==0:
            d[s[i][0]] = 0
            d[s[i][1]] = 2
            ans.append(s[i][1])
        else:
            ans.append(s[i][0])
    elif d[s[i][0]] >= d[s[i][1]]:
        d[s[i][0]] = d[s[i][0]] - 1
        d[s[i][1]] = d[s[i][1]] + 1
        ans.append(s[i][1])
    else:
        d[s[i][0]] = d[s[i][0]] + 1
        d[s[i][1]] = d[s[i][1]] - 1
        ans.append(s[i][0])

for i in range(n+1):
