Homework 3a - Str Warmups

This is just a few warmup functions. All parts of HW3 are due Wed Jan 29th at 11:55 pm.

A note on range() and reversed():

Here is the standard for/i/range loop

for i in range(10):

This runs i through the numbers 0, 1, 2, ... 8, 9

The reversed() function takes in a sequence and reverses it, so the loop

for i in reversed(range(10)):

runs i through the same numbers in reverse order 9, 8, 7, .... 2, 1, 0

These problems can be solved in many ways, but in this case, the instructions say to solve them using for/i/range loops.
