Coding Challenge #21

Coding Challenge Series / Technical Interview Series

Create a function which copies byte data from a source location to a destination location (you might use pointers or an array depending on the programming language). The function must copy using this pattern: 8 bytes, skip 8 bytes, 4 bytes, skip 8 bytes, 8 bytes, … repeat (+8,-8,+4,-8….).

Bonus points for really nailing the performance of this one.


(Are you enjoying this series? I’d appreciate a comment if you’d like me to continue the series. It takes more time than I’d like to admit to create and post these entries every week.)
