package Amcat.pattern;

public class Number1 {

 public static void patternGenerator(int n) {
  
  int val = n;// start number
  boolean flag = true;//used to inc. and dec. val
  for (int i = 1; i <= n * 2; i++) {
   
   for (int j = 1; i <= n && j <= i; j++)
   {
    System.out.print(val);
    flag = true;
   }
   if (flag)
    val++;
   System.out.println();
   if (!flag || i == n)
    val--;
   for (int j = i; i >= n && j < n * 2; j++) {
    System.out.print(val);
    flag = false;
   }

  }

 }

 public static void main(String[] args) {
  patternGenerator(6);
}

}
