I鈥檓 currently job hunting and looking for a platform to prep for interviews.
Leetcode is nice but it locks hard problems behind a paywall that I honestly can鈥檛 afford right now.
I mean I can still read the problem from https://leetcode.ca/, but it鈥檚 hard to test it against a good set of test cases.
Please share alternative portals with a decent hard problem collection with testcases
CodeWars is way cheaper.
Would Project Euler satisfy your requirements?
I鈥檝e tried Euler years ago, it鈥檚 got great problems, but not very easy to test your solutions.
I registered on Codewars now and attempted a few Katas. The portal is pretty barebones and that sits fine with me! However I don鈥檛 see the same caliber of problems at higher difficulties that leetcode offer. The problems are also lacking (Trees are not a tag!) - for instance Dynamic programming only has 3 problems across the site. Am I missing something? Will I unlock all the problems after upgrading to Red?
Actually, you made me wonder if CodeWars and LeetCode are comparable. I do remember CodeWars having relatively simple problems.
