C++ :

#include <bits/stdc++.h>
using namespace std;

int a[20],i,x,ma,n;

int main() {
	cin>>n;
	for(i = 1;i <= n;i++){
		cin>>x;
		a[x]++;
	}
	
	ma = 0;
	for(i = 1;i <= 10;i++){
		if(a[i] > a[ma]){
			ma = i;
		}
	}
	cout<<ma;
	return 0;
}

Java :

import java.util.Scanner;
public class Main{
public static void main (String[] args){
	Scanner sc = new Scanner(System.in);
	int n = sc.nextInt();
	int[] a = new int[n];
	int[] b = new int[11];
	int m = 0;
	for(int i = 0; i < n; i++) {
		a[i] = sc.nextInt();
		b[a[i]]++;
	}
	for(int i = 1 ; i < 11; i++ ) {
		if(b[i] > b[m]){
			m = i;
		}
	}
	System.out.print(m);
	
	

}
}

Python :

n = int(input())
a = input().split()
b = [0] * 11
x = 0
# 类型转换
for i in range(0, n):
    a[i] = int(a[i])
    k = a[i]
    b[k] += 1
x = max(b)
for i in range(1, 11):
    if b[i] > 0 and b[i] == x:
        print(i)
