C :

#include<stdio.h>

int main()
{
	long long t,n;
	scanf("%lld",&t);
	while(t--)
	{
		scanf("%lld",&n);
		printf("%lld\n",n*n%10000);
	}
	return 0;
}

C++ :

#include<stdio.h>

int main()
{
	long long t,n;
	scanf("%lld",&t);
	while(t--)
	{
		scanf("%lld",&n);
		printf("%lld\n",n*n%10000);
	}
	return 0;
}

Pascal :

program p1075;
var i,j,k,t:longint;
    n:int64;
begin
  readln(t);
  for i:=1 to t do
   begin
     readln(n);
     writeln(n*n mod 10000);
   end;
end.

Java :

import java.util.*;
public class Main{
    public static void main(String[] args){
        Scanner in=new Scanner(System.in);
        long t =in.nextLong();
        for(int i=0;i<t;i++){
            long n=in.nextLong();
            long s=0;
            long v=1,y;
            for(int j=1;j<=n;j++){
                s=(s+v)%10000;
                v=v+2;

Python :

import sys

for line in sys.stdin:
    data = int(line.split()[0])
    if l != 1:
       print data*data%10000
    l +=1
