2 Write a Python program for implementing binary search on a sorted array of N numbers.

Write a python function, find_pairs_of_numbers() which accepts a list of positive integers with no repetitions and returns count of pairs of numbers in the list that adds up to n The function should return 0, if no such pairs are found in the list..

Sample Input

1,2,7,4,5,6 0,316

3,4,1,8,5,9,0,619

4. A teacher is in the process of generating few reports based on the marks scored by the

students of her class in a project-based assessment. Assume that the marks of her 10 students are available in a tuple. The marks are out of 25.

Write a python program to implement the following functions:

a) find more than average(): Find and return the percentage of students who have scored more than the average mark of the class.

b) generate frequency(): Find how many students have scored the same marks. For example, how many have scored 0, how many have scored 1, how many have scored 3. how many have scored 25. The result should be populated in a list and returned. c) sort marks(): Sort the marks in the increasing order from 0 to 25. The sorte

values should be populated in a list and returned

Exercises:

3. Care hospital wants to know the medical specialty visited by the maximum number of patients Assume that the patient id of the patient along with the medical specialty visited by the patient is stored in a list. The details of the medical specialties are stored in a dictionary as follows:

"P":"Pediatrics",

"O""Orthopedics".

EVENT

return the name of the specialty.

Also write the pytest test cases to test the program,

Note

Assume that there is always only one medical specialty which is visited by maximum number

of patients
