I don't have a good recommendation for your needs. However, there are a few books that might be close: 1. Programming Pearls by Jon Benley. 2. Programming Challenges by Steven Skiena. 3. Algorithmic puzzles by Levitin. The first two are mostly programming focus. I have not read the 3rd book, but I have a good idea what it is about (based on other books by Levitin); it should be good.
