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...
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. ...
080.remove-duplicates-from-sorted-array-ii Follow up for "Remove Duplicates": What if duplicates are allowed at most twice? For example, Given sorted array nums = [1,1,1,2,2,3], Your function should return length = 5, with the first five elements of nums being 1, 1, 2, 2 and ...
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 ...
