Please check my code:
import java.util.Scanner;
public class Main {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int val = 1;
int nsy = 2;
int row = 1;
while(row <= n) {
if(row == 1)
System.out.print("1");
else {
for(int csy = 1; csy <= nsy; csy++) {
if(csy == 1 || csy == nsy)
System.out.print(val);
else
System.out.print("0");
}
}
System.out.println();
val++;
nsy++;
row++;
}
}
}
I am getting errors as follows:
