Given a number n (1<=n<=9), return a left justified numeric matrix p with all the palindromes of the form 1 to n and back to 1. Use 0 for empty values. Similarly return the square root matrix in the same form.

Example

 n=2;

 p=[1 0 0; 1 2 1];

 r=[1 0 0; 1 1 0];

The example given is at odds with the test suite: r should always be an n-by-n matrix, so for n = 2, r = [1 0; 1 1] is correct.
