Algorithm design and problem-solving

True or false?

It does not matter what order the stages of the PDLC are carried out in, as long as they are all carried out.

• true

• false

_______________is the first step of the PDLC, where the problem is broken down and understood.

__________________is the second step of the PDLC, where the solution to the problem is planned in detail.

___________________is the third stage of the PDLC, where the planned solution is implemented.

___________________is the fourth stage of the PDLC, where you test to see if your solution solves the problem as intended.
