#include <stdio.h>
void main()
     {
      int year, leap;
      scanf("%d",&year);
      if(year%4!=0)
	   leap=0;
        else if(year%100!=0)
	   leap=1;
        else if(year%400!=0)
	   leap=0;
        else
leap=1;

      if (leap)
	printf("%d is ",year);
      else
	printf("%d is not ",year);
      printf("a leap year.\n");
