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. Example 1: Given nums = [1,1,2...
1. UsingCollection.removeIf()to Remove Duplicates from OriginalList TheremoveIf()method removes all of the elements of this collection that satisfy a specifiedPredicate. Each matching element is removed usingIterator.remove(). If the collection’s iterator does not support removal, then anUnsupportedOp...

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 ...
