Then, install WhatsApp on the new device and verify your phone number. During the setup process, you will be prompted to restore your chat history from the backup. Once you select the backup file, your chat history will be merged onto the new device. Keep in mind that this process will overwrite any existing chat history on the new device, so make sure to back up any important chats before proceeding. **

Merge Sort works by dividing the unsorted list into smaller sublists, sorting those sublists recursively, and then merging them back together in the correct order.

This algorithm is efficient and has a time complexity of O(n log n) in the worst-case scenario. **
