Largely, the process to find the duplicates using Collections is simlar to previous approach. 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.s...
Now we can use the aboveMapto know the occurrences of each char and decide which chars are duplicates or unique. //duplicate charsListduplicateChars=bag.keySet().stream().filter(k->bag.get(k)>1).collect(Collectors.toList());System.out.println(duplicateChars);//[a, o] We can also fi...

SetsFast lookups without duplicatesIdeal for situations where uniqueness is crucial, and fast membership testing is required. DictionariesKey-value lookups (faster than lists)Perfect for mapping keys to values, offering fast access times and efficient insertion and deletion operations. ...
if Duplicates <> dupAccept then L := I; end; end; end; Index := L; end; 还是被吓了一跳,怎么感觉这么复杂,仔细一看才明白,原来是个折半查找算法。呵呵。 L,H变量分别代表Low和High,(L + H) shr 1就是求中间值的,完全等于(L + H) div 2,对于二进制, ...
1. We need a hash table to determine duplicates. If we use hash set, we cannot store the directories of each content. For convinience, we use a hash map. The mapping is content -> directories(including file name) which is Stirng -> Set<String>. We we finish scanning the whole array...
Disadvantage: there might be flase positive duplicates, because two different files might share the same checkSum. Question-3: If you can only read the file by 1kb each time, how will you modify your solution? Answer: makeHashQuick Function is quick but memory hungry, might likely to run wi...
