I don't understand the question. And I don't know where to start

Question

Create a method addArray(int[ ] A)<\/code> that accepts a 1-dimensional array of integers. Each of the integers in the array is considered a part of a bigger whole integer, and this bigger integer is represented by the entire array. The method will add 1 to the whole integer representation and returns the corresponding array representation of the sum. For example, if A=[1,2,3]<\/code> then the whole number is 123. The method will return a new array, A0=[1,2,4]<\/code> .

Answer 1

I assume that his is a test question, so I will just give a clue.

You can create a string and then cast to a number or you could create a new number directly, but you will need to remember to put the number in the appropriate column (10, 100, 1000).
