I don't get how IQ could be considered inherent. It's a test, so results are defined by talent and training. A person who spent a month solving the types of problems present in an IQ test will certainly get a higher score. By, the way, you did become better at coding by solving Leetcode problems, cause now you can easily spot them in the wild and use a proper algorithm instead of some naive solution.
