QUESTION:
Using the above code, what does the method addBonues()do?
Please be as detailed as possible. Thank you!
Explanation / Answer
The addBonus() method adds the bonus points to the array1 array.
The shouldAdd array stores two values:
So, the loop iterates through the entire array1 array and at each step it checkks if the bonus is to be added. If shouldAdd[i] is 1, then the bonus points are added. But otherwise, no bonus points are added to that element of array1.
