Solution in C (judge verdict: Time Limit Exceeded)

#include <stdio.h>

int main()
{
	int i, j, m[10], max, max_num;
	
	for (i = 0; i <= 10;) {
		scanf("%d", &m[i]);
		if (m[i] >= 0 && m[i] <= 10000)
			i++;
		else
			printf("too low or high\n");
	}
	
	putchar('\n');
	
	max = m[0];
	for (j = 0; j < 3; j++) {
		for (i = 0; i <= 10; i++) {
			if (m[i] > max) {
				max = m[i];
				max_num = i;
			}
		}
		printf("%d\n", max);
		m[max_num] = 0;
		max = m[0];
	}
	
	return 0;
