#1

import java.util.;
public class Main {
public static void main(String args[]) {
boolean status = false;
Scanner cin = new Scanner(System.in);
int n = cin.nextInt();
for(int i = 1;i<=100;i++){
for(int j = 1;j<=100;j++){
if(ii+jj == nn&&i<j){
System.out.print(i + " "+ j);
}else if(ii + nn == jj){
System.out.print(i + " "+ j);
}else if(jj + nn == ii){
System.out.print(j+ " " + i);
}else{
status = true;
}
}
}
if(status){
System.out.println(-1);
}
}
}====what’s the error in code

#2

else if (n % 2 == 0) {
System.out.println(((n * n) / 4) - 1 + " " + (((n * n) / 4) + 1));
}

    else if (n % 2 != 0) {

        System.out.println((n * n - 1) / 2 + " " + (n * n + 1) / 2);
    }
