In this task you will be given a list of integers. For every element in the list, if the element is positive you should multiply it by 2.  If the element is negative you should multiply it by -3. The output should be a list of integers that is the result of applying that logic to the input list.
 Note: A list is presented with comma separated numbers inside two brackets.
