3. Coach Kyle has some top athletes who have the potential to qualify for Olympics. They have been training very had for the 5000 and 10000 meters running competition. The coach has been recording their timings for each 1000 meters. In the practice sessions, each athlete runs a distance in multiples of 1000 meters and the coach records their time for every 1000 meters.
Write a python program that reads a text file consisting of following data:

Alice 3:15, 2:45, 3:30, 2:27, 3:42

Bob 2:25, 3:15, 3:20, 2:57, 2:42, 3:27

Charlie 2:45, 3:25, 3:50, 2:27, 2:52, 3:12

David 2:15, 3:35, 3:10, 2:47

1. Use a function to read the data from the file

2. Implement the logic using Dictionary, List, and String.

3. Use maketrans and translate functions to replace commas with spaces

4. Use split function to split the timings into individual elements of a list

5. Perform necessary calculations to display min, max, and avg timings of each athlete

This first part of the film shows the early history of motion pictures. how accurate do you think the portrayal of the early motion picture industry is? why? is historical accuracy important in films and theatre productions? explain. in the scene where don is going to the party (starting at time code 14: 51), we see a street scene as he first rides with cosmo and then with kathy. what aspects did the filmmaker include to make the scene look and feel like don, cosmo, and kathy are riding in a car on a street? think about elements such as scenery, sound, props, lighting, and so on. a "talkie" picture is shown starting around time code 21: 15. how does the audience in the film react to the "talkie"? what influence do audiences have on film and theatre performances? how do film and theatre actors influence audiences? in the musical scene with cosmo (starting at time code 27: 00), how does the actor use props? what is the result? do you think the use of props effectively fulfilled the artistic vision for this musical number? why or why not?

Name the range function that would generate the following list of integers values: 0,1,2,3,4,5.

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
