There are two types of programming challenges - code completion and help-free challenges. Code completion problems are designed for beginners to get a grasp of syntax while practicing basic algorithms.

Help-free challenges are for more advanced programmers; help-free challenges are designed to stimulate your creative thought processes while programming. If you're confident of your abilities, see if you can get these problems. Every problem has a given answer.
