Question: A running club has instigated a six week training program for a particular set of club members. At the first session the time each member

A running club has instigated a six week training program for a particular set of club members. At the first session the time each member takes to run 400m is noted. At the end of the six weeks these timings are repeated. The club intends to give a prize to the member who has reduced their time over 400m the most. It needs a program that will allow the necessary data to be entered and that will give the reduction in running time for each member and the name of the member with the greatest reduction. The club already has a list of the names of the members as a .txt file.

The club coach has agreed to help with this program and has gathered the information in the following list:

What data must be supplied?

- user input
times for first run
times for second run
- data that already exists
names of runners

What is required of the program?

Calculate the reduction in running time for each runner
Find the runner with the greatest reduction

The coach has decided to store the names of the runners and the two running times for each runner in three parallel lists. She writes down a first version of an algorithm:

Input the running times for each runner
Calculate the reduction in running time for each runner
Find the runner with the greatest reduction
Output the name of the runner

She then refines the algorithm:
Repeat (number of runners) times
input the first running time
input the second running time
For each runner
calculate the reduction as first running time - second running time
Find the runner with the greatest reduction
Output the name of the runner

Questions:
a. Select the sub-process that still needs to be refined.

Choose... Input the second running time Output the name of the runner

b. 'Input the running times for each runner' might be chosen to be implemented as a component because it is a reasonably substantial task. Select another characteristic of the task that makes it suitable to be implemented as a component.

Choose... Input the second running time Output the name of the runner Input the first running time Find the runner with the greatest reduction Calculate the reduction Input the list of the names of the runners th er
