Solution in C (judge verdict: Time Limit Exceeded)

int main(){
    int a[10],i,max[3],tmp;
    for(i=0;i<10;i++){
        scanf("%d",&a[i]);
        if(a[i]<=0 || a[i]>=10000){
            i--;
        }
    }
    max[0]=a[0];
    max[1]=a[1];
    max[2]=a[2];
    for(i=3;i<10;i++){
        if(max[2]<a[i]){
            tmp=a[i];
            a[i]=max[2];
            max[2]=tmp;
            if(max[1]<max[2]){
                tmp=max[2];
                max[2]=max[1];
                max[1]=tmp;
