This is just me having some fun attempting to come up with solutions to Leetcode problems.
I'm honestly against the entire idea of using random Leetcode problems when attempting to hire candidates as it does not truly provide insight on a developers ability to handle day to day real life problems.
If anything, a general compiled list of questions related to the actual role a candidate is applying for should be used within Leetcode. By doing so you can easily gather true information about how a candidate thinks through problem solving.
