What is the difference between List and sets?
What is the difference between an array and a list?
The main difference between an array and a list is how they internally store the data. In an array the data is stored sequentially in memory. So if you have an array of integers. int array[10]; In memory each element (array[0] to array[9]) is stored one after another. For a list this isn’t true.
