Hardest part is to understand what to return. Does it want a int? a list? By seeing the Output in the descrpition it looks like it want both, but the function asks for a int.

[@vadymchecherinda2858]

For me the most complicated part is how to come to this solution. I mean algorithm. For me its not obvious. This is the most hard part.

[@GregHogg]

Yeah for sure

while val in nums: nums.remove(val) k=len(nums) return k What about this Solution?? 👆☝

the time taken is slightly higher and sometimes they might ask you to not to use inbuilt functions (like remove) to understand your knowledge over the data structures. ( your solution is completely right no doubt about it but sometimes the interviewer might ask you to do it without the inbuilt function and do the same problem to know your understanding over the concept. )
