I also don't like the way how frequent now it has become having same questions with different constraints in leetcode contests seems like they lack quality problems
Yes, it would be better if contest has only one version. (based on other problems in contest they can add either easy/hard version) They can add both versions in practice.
adding testcases that cause hashmap collisions will TLE, so that's on problem setter if it worked in contest it should continue working. But for using hashing when there are so many deterministic string matching algorithms? If they want a correct solution then it does seem fine, but again if the test was added specifically to hurt people with good ranks then it's bad.
Why is hashing not a correct soln? Tests were specifically add (maybe proposed by others?) against people who were at top. It is not realistically possible to look at all submissions and generate testcases against their base and mod.
A. problem 1 B. problem 2. OR problem 1.2 C. possible problem 3 or problem 1.2 D. possible problem 2.2 OR problem 1.2 OR problem 4 Came here to prep for companies, had to start doing cf :)

Please tell me how i can improve my cp?
tell me good resources ?
Step 1 - Join discord discord.gg/HKFgRWmWNY
Step 2 - Check roadmap-to-red-in-2-mins channel.
usaco problems in the usaco guide are too long - heavy implementation comparing to cses or cf , are they a must?@@aryanc403
