What wrong in my submission its working fine

#1

Scanner sc = new Scanner(System.in);

	int n = sc.nextInt();
	double x =0;
	double y =0;
	double result =0;
	double sqn = n*n;
	
	if(n%2!=0) {
		
		double sq = sqn/2;
		
		 x = (double) (sq-0.5);
		 y = (double)(sq+0.5);
		
		 result = y*y - x*x;
		 if (result == sqn) {
				System.out.println((int)x+" "+(int)y);
			}else {
				System.out.println("-1");
			}
	}
	else {
		
		
		x = (int) (Math.pow(n/2, 2)-1);
		y = (int) (Math.pow(n/2, 2)+1);
		
		result = y*y - x*x;
		
		if (result == sqn) {
			System.out.println((int)x+" "+(int)y);
		}else {
			System.out.println("-1");
		}
	}
	
	
}

}

Let the given number be n>2.

For n even, n2+((n/2)2–1)2=((n/2)2+1)2.

For n odd, n2+((n2–1)/2)2=((n2+1)/2)2.

i found this formula, pls check it once
