Side Diagonal

Statement

Given an integer n, create a two-dimensional array of size (n×n) and populate it as follows, with spaces between each character:
  • The positions on the minor diagonal (from the upper right to the lower left corner) receive 1 .
  • The positions above this diagonal recieve 0 .
  • The positions below the diagonal receive 2 .
Print the elements of the resulting array

The diagonal parallel to the main

Statement

Given an integer n, produce a two-dimensional array of size and complete it according to the following rules, and print with a single space between characters:
  • On the main diagonal write .
  • On the diagonals adjacent to the main, write .
  • On the next adjacent diagonals write and so forth.
Print the elements of the resulting array.
sample 
n=7
0 1 2 3 4 5 6
1 0 1 2 3 4 5
2 1 0 1 2 3 4
3 2 1 0 1 2 3
4 3 2 1 0 1 2
5 4 3 2 1 0 1
6 5 4 3 2 1 0

Chess Board

Given two numbers  and . Create a two-dimensional array of size and populate it with the characters "." and "*" in a checkerboard pattern. The top left corner should have the character "." 


above figure shows the main chess board pattern, note that "." means white and "*" means black
