4. Function name: find_smallest_positive_number Parameter: A list of integer values. Return value: An integer value that is the smallest number greater than 0 in the list or None if there are no positive numbers in the list. Example: 'Find_smallest_positive_number( [2, -4, 5]) should return 2. Note: This one most closely matches some of the examples done in lecture for optimization loops. Work out some examples by hand. Make sure you can state your problem-solving approach in words before trying to code. If you are asking for help with code, be ready to show examples worked by hand and be ready to state how you think you are solving it. Do notjump to coding without doing these preparatory steps
