tester [92]

<u>Explanation:</u>

Remember, an algorithm in simple words means a set of instructions or steps to be followed in other to solve a problem.

Note, to decide which commute is cheaper, it means the output of the algorithm should be the cheaper way to commute.

Using pseudocode do the following;

  • determine the inputs and outputs of the problem
  • arrange the identified problem into micro-tasks
  • describe each micro-tasks in the pseudocode
  • Test the pseudocode by solving the problem.

Write an application that displays every perfect number from 1 through 1,000. A perfect number is one that equals the sum of all
matrenka [14]

Answer:

Written in Python

for num in range(1,1001):

    sum=0

    for j in range(1,num+1):

         if num%j==0:

              sum = sum + j

                   if num == sum:

                        print(str(num)+" is a perfect number")

Explanation:

This line gets the range from 1 to 1000

for num in range(1,1001):

This line initializes sum to 0 for each number 1 to 1000

    sum=0

This line gets the divisor for each number 1 to 1000

    for j in range(1,num+1):

This following if condition line checks for divisor of each number

<em>          if num%j==0: </em>

<em>               sum = sum + j </em>

The following if condition checks for perfect number

                   if num == sum:

                        print(str(num)+" is a perfect number")
