Given a sorted array, 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 in place with constant memory. For example, Given input array A = [1,1,2], Your function should retur...
With this method, we do not have to initially define an empty array. Thefilter()method will return an array so we just assign this array to a value. letmyData=[ 1,2,2,4,5,5,5,7,'Hello','World',true,false];letduplicateValues=myData.filter((item,index)=>{returnmyData.indexOf(i...

Removing Duplicate Elements from Array We need to remove duplicate elements from array so that each element only appears once (all the values in the array should become unique). Example Input: [1,2,2,3,4,4,4,5,5] Output: [1,2,3,4,5] Explanation The frequency of each element is sh...
If we remove all the duplicate elements from theSet, it will contain only the unique elements. distinctElementsSet.removeAll(Arrays.asList(duplicateElementsArray));Integer[]uniqueElementsArray=distinctElementsSet.toArray(Integer[]::new);System.out.println("Unique elements in the array : "+Arrays....
