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: Web19 apr 2024 · First, think about what the array might look like if we extended it to contain all the elements, including the duplicate zeros. It would be an array of length arr.length + number_of_zeros_in_the_array. If we had an array that could contain the dulicate zeros and the existing elements, it would look like this: The length of the first array is 8. rich orlich
