1299 - Replace Elements with Greatest Element on Right Side\. Easy Given an array `arr`, replace every element in that array with the greatest element among the elements to its right, and replace the last element with `-1`. After doing so, return the array. **Example 1:** **Input:** arr = [17,18,5,4,6,1] **Output:** [18,6,6,6,1,-1] **Explanation:** - index 0 --> the greatest element to the right of index 0 is index 1 (18). - index 1 --> the greatest element to the right of index 1 is index 4 (6). - index 2 --> the greatest element to the right of index 2 is index 4 (6). - index 3 --> the greatest element to the right of index 3 is index 4 (6). - index 4 --> the greatest element to the right of index 4 is index 5 (1). - index 5 --> there are no elements to the right of index 5, so we put -1. **Example 2:** **Input:** arr = [400] **Output:** [-1] **Explanation:** There are no elements to the right of index 0. **Constraints:** * 1 <= arr.length <= 104 * 1 <= arr[i] <= 105
