Spiral Matrix Pattern
Given an integer N, generate and print an N x N matrix filled clockwise with numbers 1 to N² in spiral order. Separate numbers on each row with a single space.
Input Format
A single integer N.
Output Format
Print N rows with N space-separated numbers.
Constraints:1 <= N <= 10

Notice how character spacing and row counts scale systematically based on the input N.
Concrete Examples
Example 1
Input:
4
Output:
1 2 3 4 12 13 14 5 11 16 15 6 10 9 8 7
Explanation: Fills 1 to 16 in a clockwise inward spiral.
Example 2
Input:
3
Output:
1 2 3 8 9 4 7 6 5
Explanation: Fills 1 to 9 in spiral order.
