Sort even | Python3 Program to sort even - placed elements in increasing and odd - placed in decreasing order with constant space complexity.
first odd index.
last index.
if last index is odd.
decrement j to even index.
swapping till half of array.
Sort first half in increasing.
Sort second half in decreasing.
Driver Program"
How can the above be solved in Python?

=====
Can you provide a code to sort even and the other steps required?
