X-Shaped Matrix

Given an odd integer n, print an X-shaped matrix of size n x n where the two diagonals are filled with the character '+' and the remaining positions are filled with '-'.

More formally, for each cell \( (i,j) \) in the matrix (using 0-indexed rows and columns), if \( i = j \) or \( i+j = n-1 \), print '+', otherwise print '-'.

For example, when \( n = 5 \), the output should be:

+---+
-+-+-
--+--
-+-+-
+---+

inputFormat

The input consists of a single line containing an odd integer n (\( n \geq 1 \)).

outputFormat

Output the resulting X-shaped matrix with n rows, where each row is printed on a new line.
