Intro Fixed Replacements

This intro problem practices REPLACE. REPLACE swaps text at a specific starting position for a specific number of characters. Update the output cells so each code replaces characters 4 and 5 with "XX". See Examples

Your solution should use cell references so it updates automatically if the input cells change values.
