-/**
- * 1089. Duplicate Zeros
- *
- * Given a fixed length array arr of integers, duplicate each occurrence of zero, shifting the remaining elements to the right.
- *
- * Note that elements beyond the length of the original array are not written.
- *
- * Do the above modifications to the input array in place, do not return anything from your function.
- *
- * Example 1:
- * Input: [1,0,2,3,0,4,5,0]
- * Output: null
- * Explanation: After calling your function, the input array is modified to: [1,0,0,2,3,0,0,4]
- *
- * Example 2:
- * Input: [1,2,3]
- * Output: null
- * Explanation: After calling your function, the input array is modified to: [1,2,3]
- *
- * Note:
- *
- * 1 <= arr.length <= 10000
- * 0 <= arr[i] <= 9
- * */
