Problem:
Mode Value

Your task is to write a program which reads a sequence of integers and prints mode values of the sequence.
The mode value is the element which occurs most frequently.

Input

A sequence of integers ai (1 ≤ ai ≤ 100). The number of integers is less than or equals to 100.

Output

Print the mode values. If there are several mode values, print them in ascending order.

Sample Input

5
6
3
5
8
7
5
3
9
7
3
4

Output for the Sample Input

3
5

For example, 3 and 5 respectively occur three times, 7 occurs two times, and others occur only one. So, the mode values are 3 and 5.

Solution in C (judge verdict: Time Limit Exceeded)

#include<stdio.h>
int main(void){
    int a,i,b[100]={0},j,c;
    for(i=0;;i++){
        scanf("%d",&a);
        b[a]++;

    }
    for(i=1;i<101;i++){
        for(j=i+1;j<101;j++){
            if(b[i]<b[j]){
                c=b[i];
                b[i]=b[j];
                b[j]=c;

            }
        }
    }
    for(i=1;i<101;i++){
        if(b[i]=b[1]){
    printf("%d\n",b[i]);
        }
    }
return 0;
}
