We start with splitting the string and collecting all words in aList. Then we use theHashSet.add()method to check if the word is unique or duplicate. List<String>wordsList=Arrays.asList(sentence.split(" "));Set<String>tempSet=newHashSet<>();List<String>duplicateWords=newArrayList<>();...
//duplicate charsListduplicateChars=bag.keySet().stream().filter(k->bag.get(k)>1).collect(Collectors.toList());System.out.println(duplicateChars);//[a, o] We can also find the duplicate characters and their count of occurrences in this string. Map<Character,Integer>duplicateCharsWithCount=b...
Find the Duplicate Number Given an array nums containing n + 1 integers where each integer is between 1 and n (inclusive), prove that at least one duplicate number must exist. Assume that there is only one duplicate number, find the duplicate one. Note: You must not modify the array (as...

Now,we aim to find the keys with duplicate values, grouping different developers that use the same operating system in aSet: Map<String, Set<String>> EXPECTED = Map.of( "Linux", Set.of("Kai", "David"), "Windows", Set.of("Saajan", "Kevin"), ...
