Arraysare a fundamental way of organizing data in programming that provides a systematic way to store and organize elements of the same data type. What if there are duplicate elements in an array? Without considering duplicates, storing an array of (n) elements requires (O(n)) space, accounti...
Thebrute force methodis the simplest method to find duplicates in a List. It involves looping through each element of the List and comparing it with other elements to check if there are any duplicates. Here’s an example implementation: ...

Alternatively, we can use one of the Java Set implementations to deduplicate a Java List.Java Setis a distinct collectionof elements. Please note that we can use HashSet to remove duplicate elements from a List, but it is an unordered collection and will not honour the order of the elements...

add the a[n-1] element into res array We will print the elements present in the index range from i=0 to i=k-1 before returning the value of k, which is now the total number of unique elements in the array. Code Implementation C++ Java Python #include<bits/stdc++.h> using namesp...
Let's try brute-force first: For each element in the array, compare it with eachotherelement in the array. If the two elements are equal, we've found our duplicate. Now, before you skip the next paragraph, keep in mind that there are several books that make - small, but real - bug...
