Efficiency vs Efficacy

• What's the difference between them?
• Which one is required for the push_swap project?

Real Case Study

Let's suppose that you need to commute from your house to your work by car, but here is a traffic jam ahead, like Mr. Goofy from Disney: https://www.youtube.com/watch?v=_Tlk6e61E6w

Efficiency - The goal, whatever it takes

You can drive like Mr. Goofy but at crazy mode accelerating a lot, changing lanes every second, hitting brakes... and eventually arriving at work.

Did you make the goal? Yes.

But probably, you burned some really important resources from your car (gas, oil, brakes, engine), and from yourself (mental health, stress, anxiety, etc...)

Efficacy - The goal, with minimal resources

However, you can also goes like the initial state from Mr. Goofy: a pleasant guy which could find another path or even just wait with pacience and love the innevitable truth: there will be a traffic jam ahead.

Did you make the goal? Yes.

Without burning your brain, tires and fuel unnecessarily.

Push_Swap - Which one is required?

Push Swap is about a program that sort numbers from user's input, but also:

• has 2 stacks to store the given numbers;
• has 11 basic functions to move the numbers between stacks;
• calculates the cost of every number, with a given target
• search for the cheapest moviment
• do the moviments to sort the list Even with cost calculation, this program works only with efficiency mode (the goal, whatever it takes). The project's algorithm was created by Mia Combeau: https://github.com/mcombeau/push_swap
