text: ﻿Zero Arrow Pattern Printing
  The program must accept an integer N as the input. The program must print the pattern of (2*N)-1 lines based on the following conditions.
  - Each row of the pattern contains N characters.
  - In the 1st row, the Nth character is 0 and the remaining characters are asterisks.
  - In the 2nd row, the Nth, (N-1)th characters are 0 and the remaining characters are asterisks.
  - In the 3rd row, the Nth, (N-2)th characters are 0 and the remaining characters are asterisks.
  - Similarly, the first N lines of the pattern are printed.
  - In the (N+1)th row, the Nth, 2nd characters are 0 and the remaining characters are asterisks.
  - In the (N+2)th row, the Nth, 3rd characters are 0 and the remaining characters are asterisks.
  - Similarly, the remaining lines of the pattern are printed.
  Note: All characters in each row must be separated by a space.
  Boundary Condition(s):
  3 <= N <= 100
  Input Format:
  The first line contains N.
  Output Format:
  The first (2*N)-1 lines containing the desired pattern as per the given conditions.
  Example Input/Output 1:
  Input:
  3
  Output:
  * * 0
  * 0 0
  0 * 0
  * 0 0
  * * 0
  Explanation:
  Here N = 3, so the pattern contains 5 lines ((2*3)-1).
  In the 1st row, the 3rd character is 0 and the remaining characters are asterisks.
  * * 0
  In the 2nd row, the 3rd, 2nd characters are 0 and the remaining character is an asterisk.
  * 0 0
  In the 3rd row, the 3rd, 1st characters are 0 and the remaining character is an asterisk.
  0 * 0
  In the 4th row, the 3rd, 2nd characters are 0 and the remaining character is an asterisk.
  * 0 0
  In the 5th row, the 3rd character is 0 and the remaining characters are asterisks.
  * * 0
  Example Input/Output 2:
  Input:
  5
  Output:
  * * * * 0
  * * * 0 0
  * * 0 * 0
  * 0 * * 0
  0 * * * 0
  * 0 * * 0
  * * 0 * 0
  * * * 0 0
  * * * * 0
