Given a sorted array nums, remove the duplicates in-place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory. ...
We sort the array in the first step, which takes O(NlogN) time. After that, we execute the loop from 1 to n-1, which requires O(N) time. Therefore, this method’s worst-case time complexity for eliminating duplicates from the array is O(NlogN)+O(N)=O(NlogN). Auxiliary Space ...
