Thread: 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;
 
}

you can simulate it here:
JavaBat Array-1 makeLast

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;
 
}
