Write an algorithm, pseudocode and draw a flowchart of for the following problem of which the computer can compute the number of cables needed to create a network using ring topology and star topology in a sequence

Write an algorithm, pseudocode and draw a flowchart of for the following problem of which the computer can compute the number of cables needed to create a network using ring topology and star topology in a sequence.

Ring: Number of cables= N ( where N is number of devices)

Star: Number of cables= N ( where N is number of devices)
