Solution in C (judge verdict: Time Limit Exceeded)

#include <stdio.h>

int main()
{
	int a[10];

	int i, j;
	for (i = 0; i < 10; ++i)
	{
		printf("%d\n", i);
		scanf("%d", &a[i]);
	}

	for(i = 0; i < 3; ++i)
	{
		int max = 0;
		for (j = 0; j < 10; ++i)
		{
			if(max < a[j])
			{
				max = a[j];
				a[j] = -1;
			}
		}
		printf("%d\n", max);
	}

	return 0;
