Binomial coefficients are a family of positive integers that have a number of useful properties and they can be defined in several ways. one way to define them is as an indexed recursive function, c(n, k), where the "c" stands for "choice" or "combinations." in this case, the definition is as follows: c(n, 0) = 1, c(n, n) = 1, and, for 0 < k < n, c(n, k) = c(n − 1, k − 1) + c(n − 1, k). (a) show that, if we don’t use memoization, and n is even, then the running time for computing c(n, n/2) is at least 2n/2. (b) describe a scheme for computing c(n, k) using memoization. give a bigoh characterization of the number of arithmetic operations needed for computing c(n, n/2) in this case.

Write a program that reads a file consisting of students’ test scores in the range 0–200. it should then determine the number of students having scores in each of the following ranges: 0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200. output the score ranges and the number of students. (run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.)

In this lab, you complete a python program that calculates an employee's annual bonus. input is an employee's first name, last name, salary, and numeric performance rating. if the rating is 1, 2, or 3, the bonus rate used is .25, .15, or .1 respectively. if the rating is 4 or higher, the rate is 0. the employee bonus is calculated by multiplying the bonus rate by the annual salary.
