Given n (always odd), return output a that has concentric rings of the 1s and 0s around the center point. Examples:
Input n = 3
Output a is [ 1 1 1
1 0 1
1 1 1 ]
Input n = 5
Output a is [ 1 1 1 1 1
1 0 0 0 1
1 0 1 0 1
1 0 0 0 1
1 1 1 1 1]
Additional test cases have been added.
Do you know if Matrix Patterns II and Sequences & Series III will become badge eligible problem sets? Thanks!
sorry,just test for regexp solution,it really is not a proper way to do cody.
