6.4 - Sports day

Problem

A school sports day records the names of athletes and their race times.

The program should:

  • Store the athlete names and their times in two arrays.
  • Have a procedure to find and display the fastest athlete.
  • Have a procedure to count and display how many athletes ran under 12 seconds.
  • Have a procedure to search for a given athlete by name and display their time if found.

The main program should only contain calls to these three procedures.

Example run

Fastest athlete: David with a time of 10.9 seconds
Number of athletes under 12 seconds: 2
Enter the name of the athlete to search for: Carla
Carla finished in 13.2 seconds

Arrays

names = ["Alice", "Ben", "Carla", "David", "Ella"]
times = [12.4, 11.8, 13.2, 10.9, 12.0]

 

1 Display the name of the fastest athlete IN names, times
2 Display how many athletes ran under 12 seconds IN times
3 Search for a name and display their time IN names, target_name

Use the standard algorithms to solve this problem.
