The instructor first explains the concepts necessary for coding tests and provides clear explanations on how to approach problems using those concepts. In particular, I liked that they don't just teach problem-solving techniques, but clearly point out the reasons and criteria for choosing a specific algorithm after reading a problem. I was feeling lost about how to study for coding tests, but thanks to this course, I feel like I have a much better grasp of how to approach the problems. I highly recommend this lecture to anyone who, like me, is struggling to find direction on how to prepare for coding tests.
