Your task is to write a program for their inventory management system that handles a specific case in product stocking. Specifically, for every product with a stock count of zero, the system needs to duplicate this entry $($representing an order to restock$),$ shifting the subsequent product entries to the right in the inventory list. This operation must be performed in place within the existing inventory array.

Problem Statement:

Given an array inventory representing the stock count of different products in a store, where each occurrence of zero represents a product that is out of stock, duplicate each occurrence of zero $($indicating an order placed to restock that product$),$ shifting the remaining product counts to the right.

Note: Modifications should be done in place in the inventory array, and elements beyond the length of the original array should not be modified.

Input Format:

An array inventory where each element is an integer representing the stock count of a product.

Output Format:

There is no separate output array; the inventory array will be modified in place.

Examples:

Example $1$:

Input: inventory $=[4,0,1,3,0,2,5,0]$

Output: $[4,0,0,1,3,0,0,2]$

Explanation: Zeroes represent out$-$of$-$stock products. After processing, each zero is duplicated to indicate a restock order, shifting the rest of the product counts rightward.

Example $2$:

Input: inventory $=[3,2,1]$

Output: $[3,2,1]$

Explanation: There are no out$-$of$-$stock products. The inventory remains unchanged.
