Exercises: Recognising “Plans”

Before attempting these exercises, you should read the posts on specifying problems, problem-solving and algorithmic “plans”.

Exercises

1. Name the plans used in the following code, and specify the problem this function solves.

   def exercise1(numbers):
       for i, value in enumerate(numbers):
           numbers[i] = 10 * value

2. Name the plans used in the following code, and specify the problem this function solves.

   def exercise2(numbers):
       total = 0
       for value in numbers:
           cube = value ** 3
           total += cube
       return total

3. Name the plans used in the following code, and specify the problem this function solves.

   def exercise3(numbers, cutoff):
       for i, value in enumerate(numbers):
           if value >= cutoff:
               return i
       return -1

4. Name the plans used in the following code, and specify the problem this function solves.

   def exercise4(strings, max_length):
       counter = 0
       for value in strings:
           if len(value) > max_length:
               counter += 1
       return counter
