One important aspect of essentially all programming languages is branching and conditions. In Python, conditions are usually implemented with ifelse syntax. Heres an example, that prints -1 for each negative number in an array and 1 for each nonnegative number

numbers = [-9, 2.3, -11, 0] for x in numbers:

if x < 0: print(-1)

else: print(1)

-1

1

-1

1

Now, write a new solution to Exercise 3 that does not use an existing function to compute the absolute value. Replace this existing function with an ifelse condition.
