Last but not least, we are traversing the set, which, in the worst scenario, will take O(N) time (if every element is unique) As a result, this method’s worst-case time complexity to remove duplicates from an array is O(N)+O(NlogN)+O(N)=O(NlogN). Auxiliary Space Analysis For...
Given an integer array nums sorted in non-decreasing order, remove the duplicates in-place such that each unique element appears only once. The relative order of the elements should be kept the same. Then return the number of unique elements in nums. Consider the number of unique elements of...
