About

Hi, I created NeetCode.io to make coding interview prep easier!

  • The Blind 75 is a popular list of Algorithm practice problems.
  • I created the Neetcode 150 by adding 75 more problems to make a more beginner friendly and comprehensive list.
  • The Neetcode All is all of the problems I've solved on youtube.
  • Get stuck? I've created a detailed 🎥 video explanation for each problem.
  • So far we have code solutions for [Python, Java, JavaScript, C++].
