How do you solve computer science problems?

Four Main Problem Solving Steps:

  1. Understand the Problem. Solving the right problem is the most important part of problem solving.
  2. Design a Solution. Formulate an algorithm to solve your problem.
  3. Implement your Solution. Write the code to solve your problem.
  4. Check your Solution.
