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 i,j;
	int count[101]={0};
	int number;
	int counta=0;
	int flag=0;
	while(scanf("%d",&number),number!=0){
		counta++;
		count[number]++;
	}
	
	for(i=counta;i>=0;i--){
		for(j=0;j<101;j++){
			if(count[j]==i){
				printf("%d\n",j);
				flag=1;
				break;
			}
		}
	}
	if(flag==1){
		for(i=0;i<101;i++){
			if((count[i]==count[j])&&(i!=j)){
				printf("%d\n",i);
			}
		}
	}
	return 0;
}
