Chapter 2.3, Problem 2.42PP
Practice Problem 2.42 (solution page 156)
Write a function divl6 that returns the value x/16 for integer argument x. Your function should not use division, modulus, multiplication, any conditionals (if or ?:), any comparison operators (e.g., <, >, or ==), or any loops. You may assume that data type int is 32 bits long and uses a two’s-complement representation, and that right shifts are performed arithmetically.

A = vIsts - aXs - b(s - c)]
where

Write, test, and execute a function that accepts the values of a, b, and c as parameters from a
calling function, and then calculates the values of s and [s(s - a)(s - b)(s - c)]. If this quantity is
positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle,
and the function should set A = -1. The value of A should be returned by the function.
Problem 17. [ 1 point for correctness ]
Use the Design Recipe to define a function pulse_rate that has two parameters. The first is the number of seconds a nurse has counted pulses, and the second is the number of pulses counted (both ints). The function should return the pulse rate, pulses/minute, as a float. Don't forget to convert seconds to minutes! Include a Docstring.(use Python)
For example:
Test
Result
print(round(pulse_rate(30,22),1))
44.0
Use this statement to test your pulse_rate function:
assert_equal(round(pulse_rate(30, 22),1),44.0)

He wants to collapse the entire array into a single element. To do this, he can perform the operation described below any number of times. Each operation grants some points, and Ayush's total score will be the sum of the points granted over all operations he performs. Let aſi..j] denote the subarray of a starting at index i and ending at j. Define min; j to be the minimum value in a[i..j]. In one operation he can do the following: • Select any subarray a[i. j] of a of size at least 2 and replace this subarray by a single element equal to the sum of elements of the subarray. The number of points granted by such an operation, which will be added to his total score, is (j – i+1) · min;j. For example, consider an array a = [2, 3, 5]. If he selects the subarray a[1..2], his total score increases by 2 · 2 = 4 points. Now a = [5, 5].
