    Default javabat example makeLast

    Given an int array, return a new array with double the length where its last element is the same as the original array, and all the other elements are 0. The original array will be length 1 or more. Note: by default, a new int array contains all 0's.

    makeLast({4, 5, 6}) → {0, 0, 0, 0, 0, 6}
    makeLast({1, 2}) → {0, 0, 0, 2}
    makeLast({3}) → {0, 3}

    can anyone try this? i cannot get the end number. thanks.

    i cant make it.

    public int[] makeLast(int[] nums){
    int len = nums.length-1;
    int[] integerArray = new int[(nums.length * 2 -1) ]; 
     
    return  integerArray;
     
    }

    Heres the answer.

    public int[] makeLast(int[] nums){
     int len = nums.length-1;
    int[] integerArray = new int[(nums.length * 2 ) ]; 
    integerArray[integerArray.length-1] = nums[nums.length-1];
    return  integerArray;
     
    }
