I am not getting the desired output

#1

import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner sc=new Scanner(System.in);
int n=sc.nextInt();
int nst=1;
int row=1;
while(row<=n){
for(int cst=1;cst<=nst;cst++){
if(row%2>0 && cst>1 && cst<n){
System.out.print(“0”);
}
else {
System.out.print(row);
}
}
System.out.println();
nst++;
row++;
}
}
}
this question is manmohan loves pattern-2

Please share your code using the online IDE (https://ide.codingblocks.com). It’ll be easier to debug it that way.

You have a logical error in the if condition.
We need to place 0s when cst is not at the boundary of the pyramid
So the if statement should be
if(cst>1 && cst<nst){
// print(0)
}

Also, check the relation between the row number and variable row
2nd row starts with 1, 3rd row starts with 2, 4th row starts with 3, 5th row starts with 4 and so on…
Therefore in the else block we need to print row-1 rather than row. (Will have to handle the case of 1st row explicitly).
