You don't need to scan for anything. The file he attached is the scan he did. What you need to do is open it, after that you will see pointers, at the top left you will see a menu that you can press on, press on the 4 bytes choice. Now you will be able to see the value of the address under "Points to:" click on a few of them, be sure to click on the ones with the value 112 or 48. When you double click on then they are added to the main window in the bottom part. Check "Active" on them to make them freeze, and change their values to 1111. Now complete.
