Process Odd Squares

You are given a list of integers. Your task is to compute the squares of all odd numbers in the list, remove any duplicates, and then output the squares in descending order.

Input Format: A single line containing a space-separated list of integers. The list may be empty.

Output Format: A single line with the resulting squares of the odd numbers sorted in descending order, separated by spaces. If no odd numbers are present, output an empty line.

Note: The square of a number \(x\) is defined as \(x^2\).

inputFormat

The input consists of a single line with space-separated integers. For example:

1 2 3 4 5 3 1 7

outputFormat

The output is a single line containing the squares of all odd numbers from the input, with duplicates removed, sorted in descending order. For example:

49 25 9 1

## sample

1 2 3 4 5 3 1 7

49 25 9 1
