[Java][Answer] Array-1 > rotateLeft3

Given an array of ints length 3, return an array with the elements "rotated left" so {1, 2, 3} yields {2, 3, 1}.

rotateLeft3([1, 2, 3]) → [2, 3, 1]
rotateLeft3([5, 11, 9]) → [11, 9, 5]
rotateLeft3([7, 0, 0]) → [0, 0, 7]

Answer 1:

public int[] rotateLeft3(int[] nums) {
  return new int[] {nums[1],nums[2],nums[0]};
}

Answer 2:

public int[] rotateLeft3(int[] nums) {
  int[] tempArr = new int[3];
  tempArr[0] = nums[1];
  tempArr[1] = nums[2];
  tempArr[2] = nums[0];
  return tempArr;
}
