Lab 8, Extra Practice

1) table:
   i   | values[i]   | action taken (if any)
--------------------------------------------
   0   |     7       | values[0] = -1*7 = -7
   1   |     2       | none
   2   |     5       | values[2] = -1*5 = -5
   3   |     3       | values[3] = -1*3 = -3
   4   |     8       | none

The program outputs: [-7, 2, -5, -3, 8]

2)
values = [7, 2, 5, 3, 8]

i = 0
while i < len(values):
    if values[i] % 2 == 1:
        values[i] = -1 * values[i]
    i += 1

print(values)
