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

Solution

 

The diagonal parallel to the main

Statement

Given an integer n$n$, produce a two-dimensional array of size (n×n)and complete it according to the following rules, and print with a single space between characters:

• On the main diagonal write 0 .
• On the diagonals adjacent to the main, write 1 .
• On the next adjacent diagonals write 2 and so forth.

Print the elements of the resulting array.
