Do the following to normalize negative or positive inputs:

dec_value = int(input("ENTER THE DECREMENTED VALUE: "))
for i in range(10, 0, -abs(dec_value)):
    print(i)


>>> ENTER THE DECREMENTED VALUE: -5
10
5

>>> ENTER THE DECREMENTED VALUE: 5
10
5

dec_value (the step of the range) needs to be negative if the start number is larger than the end number, or it will return an empty range. If it returns an empty range, the loop won't run since there's nothing to iterate over.

If start < end, the step should be positive, else, it should be negative.
