From heaven to earth

Hey guys! Super new to coding, and very new to codechef. I’ve been testing out some of the beginner challenges and I came upon From Heaven to Earth. I came up with the code that follows. It says my answer is wrong, but I’m not too sure what’s wrong with it. Could I get some help improving my code and hopefully move toward completing this problem? (Also, I apologize if this was formatted incorrectly (very new))

public static void main(String[] args) {
	
	Scanner input = new Scanner(System.in);
	System.out.println("Enter the amount of tests you want");
	int t = input.nextInt();
	
	while(t>0) {
	if (t >= 1 || t <= 1000) {
	t-=1;
	System.out.println("Please enter 3 integers using a space or enter inbetween each one: ");
	int n = input.nextInt();
	if (n < 1 || n >= 100) {
		System.out.println("Null");
		break;
	}
	int v1 = input.nextInt();
	if (v1 < 1 || v1 >= 100) {
		System.out.println("Null");
		break;
	}
	int v2 = input.nextInt();
	if (v2 < 1 || v2 >= 100) {
		System.out.println("Null");
		break;
	}
	double t1 = (1.0*Math.sqrt(2)*n)/v1;
	double t2 = (1.0*2*n)/v2;
	if(t1 < t2){
		System.out.println("Stairs");}
	else {
		System.out.println("Elevator");}
	}
	else { System.out.println("Null"); }
	}}}

Ok!! so since code at codechef is checked by the machine, you can’t have extra lines like “Enter your input” in this question you don’t even need to check if it’s null or not, just print either Elevator or Stairs.

3

5 10 15

2 10 14

7 14 10

your output

Enter the amount of tests you want

Please enter 3 integers using a space or enter inbetween each one:

Elevator

Please enter 3 integers using a space or enter inbetween each one:

Stairs

Please enter 3 integers using a space or enter inbetween each one:

Stairs

Expected output

Elevator

Stairs

Stairs

Hope this helps!!

Deleted the stuff you don’t need

public class Main {
public static void main(String[] args) {

Scanner input = new Scanner(System.in);
int t = input.nextInt();

while(t>0) {
double t1 = (1.0*Math.sqrt(2)*n)/v1;
double t2 = (1.0*2*n)/v2;
if(t1 < t2){
    System.out.println("Stairs");}
else {
    System.out.println("Elevator");}
t--;
}
}
}
