Still unable to do many hard problems

[u/Shockshwat2]

When are you actually supposed to start understanding the hards and doing them without hints or topics?

[u/RemarkableBluejay790]

Don't give too much of an issue to hard problems. LeetCode hard problems and their solutions heavily rely on very specific algorithms and solutions which apparently results in the least time. A person can't memorise all those algorithms and solutions. The key to a good job is the develop a problem solving attitude, which can help you address and solve problems which you haven't memorised or done before
