public class LeapYearFor {
public static void main(String[] args) {
int i,j=0;
// int year=0;
for(i=1800;i<=2006;i++){
// if((year%4==0&&year%100!=0)||(year%400==0)) {
if((i%4==0&&i%100!=0)||(i%400==0)) {
j++;
// System.out.print(j+"\t");
System.out.print(i+"\t");
if(j%5==0) {System.out.println();}
}
}
// if(year%5==0) System.out.println();
