Even though the program works fine the test cases are not passed

#1

import java.util.*;
public class Main {
public static void main(String args[]) {
int n=5;
int rows=1;
int nsp=0;
while(rows<=5){
System.out.print(rows);
System.out.print("\t");
int csp=1;
while(csp<nsp){
System.out.print(0);
System.out.print("\t");
}
if(rows>1)
System.out.print(rows);
System.out.println();
rows++;
nsp++;
}

}

}

#2

import java.util.*; public class Main { public static void main(String args[]) { int n=0; int rows=1; int nsp=0; if(n>=1 &&n<100){ while(rows<=n){ System.out.print(rows); System.out.print("\t"); int csp=1; while(csp<nsp){ System.out.print(0); System.out.print("\t"); csp++; } if(rows>1) System.out.print(rows); System.out.println(); rows++; nsp++; } } else System.out.print(“enter a valid positive integer”); } }
