Now let's consider a slightly more complicated block that makes use of a loop. It accepts two numbers as inputs (start and end) and finds the sum of all of the numbers in the range from start to end, inclusive.

When start = 8 and end = 10, the value reported by this function should be 27 (8+9+10). However, the attempts at a solution shown below have some bugs. See if you can fix the bugs in the code below so that each version reports the correct sum:
