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 C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>


int main(void){
long int test,a,b,sum,i,n,l[1000],bt[100],g[100],c,cl,cb,cg;
    cl=cb=cg=0;
    scanf("%ld%ld%ld",&n,&a,&b);
    for(i=0;i<n;i++)
    {
        scanf("%ld",&c);
        if(c<=a)
        {
            cl++;
        }else{
            if(c>b)
            {
                cg++;
            }else{
                if(c>a && c<=b)
                {
                    cb++;
                }
            }
        }
    }
    if(cl>cg)
    {
        if(cg>cb)
        {
            printf("%ld",cb);
        }else{
            printf("%ld",cg);
        }
    }else{
        if(cl>cb)
        {
            printf("%lld",cb);
        }else{
            printf("%lld",cl);
        }
    }
