Plan for an algorithm that can calculate the forward pass and the backward pass (early start early finish, late start and late finish) and the critical path for only 5 activities (including first and last activities in the whole project). the inputs will be duration and precedence provided by the user. the maximum number of preceding activities is two

organize your solution in the best manner possible with comments (e. g. one section for your inputs, a section for your calculations, a section for your outputs).

use python loops and functions (at least one of each)

output should be

Design a payroll class with the following fields: • name: a string containing the employee's name • idnumber: an int representing the employee's id number • rate: a double containing the employee's hourly pay rate • hours: an int representing the number of hours this employee has worked the class should also have the following methods: • constructor: takes the employee's name and id number as arguments • accessors: allow access to all of the fields of the payroll class • mutators: let the user assign values to the fields of the payroll class • grosspay: returns the employee's gross pay, which is calculated as the number of hours worked times the hourly pay rate. write another program that demonstrates the class by creating a payroll object, then asking the user to enter the data for an employee in the order: name, id number, rate, hours. the program should then print out a statement in the following format (for example, if you had an employee named chris jacobsen with id number 11111, who works for 5 hours at $10/hr): chris jacobsen, employee number 11111, made $50.00 in gross pay. using text forming so that the gross pay is rounded to two decimal places.
