title: Suggest websites to practice C/C++ algorithms/puzzles
body: <p>I want to practice problem solving in C/C++. But I want to avoid writing the whole program from scratch. Is there any website where they give me puzzles and the code skeleton along with it and expect me to only fill a function or two to solve the problem at hand? This would save a lot of time and I can concentrate only on the problem solving part.</p>
  
  <p>Thanks.</p>
