WebIn computer programming terms, an algorithm is a set of well-defined instructions to solve a particular problem. It takes a set of input (s) and produces the desired output. For example, An algorithm to add two numbers: Take two number inputs. Add numbers using the + operator. Display the result. WebAlgorithm #1: order the jobs by decreasing value of ( P [i] - T [i] ) Algorithm #2: order the jobs by decreasing value of ( P [i] / T [i] ) For simplicity we are assuming that there are no ties. Now you have two algorithms and at least one of them is wrong. Rule out the algorithm that does not do the right thing.
