Problem:
Score : 200 points

Problem Statement

You have written N problems to hold programming contests.
The i-th problem will have a score of P_i points if used in a contest.

With these problems, you would like to hold as many contests as possible under the following condition:

A contest has three problems. The first problem has a score not greater than A points, the second has a score between A + 1 and B points (inclusive), and the third has a score not less than B + 1 points.

The same problem should not be used in multiple contests.
At most how many contests can be held?

Constraints

3 \leq N \leq 100

1 \leq P_i \leq 20 (1 \leq i \leq N)

1 \leq A < B < 20

All values in input are integers.

Input

Input is given from Standard Input in the following format:

N
A B
P_1 P_2 ... P_N

Output

Print the answer.

Sample Input 1

7
5 15
1 10 16 2 7 20 12

Sample Output 1

2

Two contests can be held by putting the first, second, third problems and the fourth, fifth, sixth problems together.

Sample Input 2

8
3 8
5 5 5 10 10 10 15 20

Sample Output 2

0

No contest can be held, because there is no problem with a score of A = 3 or less.

Sample Input 3

3
5 6
5 6 10

Sample Output 3

1

Solution in Python (3.4.3) (judge verdict: Wrong Answer)

# B
N = int(input())
A, B = [int(x) for x in input().split()]
P = [int(x) for x in input().split()]
#print(N,A,B)#
P.sort()
#print(P)#

for i in range(N):
    if P[i]>A: break
a = i # A 以下の枚数
for i in range(a,N):
    if P[i]>B: break
b = i - a # A+1以上B以下の枚数
c = N - i
#print(a,b)#
#count = min(a+1, b-a+1, N-b)
count = min(a, b, c)
print(count)
