The input will be a single line containing a positive integer (N).

Output

The output should be N rows containing the numbers in the hollow inverted half pyramid pattern.

Note: There is a space after each number.

Answer 1

N = int(input())


length = N * 2 - 1
pattern = [' '.join([str(x) for x in range(1, N + 1)])]
for i in range(1, N - 1):
    center_width = length - 2 * i - 2
    pattern.append('{0}{1}{2}'.format('1', ' ' * center_width, str(N - 1)).rjust(length , ' '))
    N -= 1
pattern.append('1'.rjust(length , ' '))
    
for i in pattern:
    print(i)
