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)

Write a computer program using any abitrary programming
longuage (MATLAB, C++, C#, Python,.) to calculate economic
load dipatch (ELD) using first order gradient method.
Note that all parameters and variables should be defined
inside the
program (at

Ayush has an array a of n integers. 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].
Ayush performs operations until only a…
