#Elements of programming interviews vs leetcode code

You may run my code here and play around with it. E.g.: public class ProgramĬonsole.WriteLine("Two most frequent numbers: " + string.Join(", ", numbers.GetMostFrequent(2))) Ĭhar letters = Ĭonsole.WriteLine("Two most common fruits: " + string.Join(", ", fruits.GetMostFrequent(2))) This generic method allows you to pass in collections of any type (and not just of the int type). Notice that there is no need to call OrderByDescending() if all of the unique groups of items in the initial collection are to be included in the final collection. (See this page for the differences between the two.)

I personally prefer the method syntax to the query syntax. Return uniqueGroups.OrderByDescending(i => i.Count()) Var uniqueGroups = inputs.GroupBy(i => i) I am mainly looking for performance optimizations.Įxpanding on answer, you may write an extension method to retrieve the X most frequently occurring items like so: public static IEnumerable GetMostFrequent(this IEnumerable inputs, int topXMostFrequent) Since C# doesn't have a MaxHeap, do you think using a SortedList can help here somehow with the performance? (remember the question limitations)

I really like this question and it took me some time to understand how to implement the bucket sorting. list equals k, because we iterate in reserve we get the biggest numbersįor (int pos = bucket.Length - 1 pos >= 0 & result.Count < k pos-) we iterate the list bucket in reverse until the number of items in the result the index represents how many times that number appeared we iterate all of the numbers and for add each number to the index in the array we allocate an array in the size of the original list of numbers Number2Count.TryGetValue(num, out var temp) Do bitwise xor of res with (start+ 2i) i.e. create a variable res to store the current xor during for loop and initialize with 0. we count how many times each number appears create a variable ind to represent index of the element of the array and initialize with 0.

Public static IList TopKFrequent(int nums, int k)ĭictionary number2Count = new Dictionary() Using ĬollectionAssert.AreEqual(expected, TopKFrequentClass.TopKFrequent(nums, k).ToArray()) Write Linq query for student list and some conditions. Array programming to write code to make all 0s in front. Async Programming difference between await Docheck() and Task.Run(async > await Docheck(). There are so many online platforms that have online judges to practice several types of problems that range from Easy to Hard.

Your algorithm's time complexity must be better than O(n log n), where Interview question for Senior Software Engineer (.NET) in Bengaluru.Write singleton class code in leetcode. 3) Elements of Programming Interviews by Adnan Aziz. You may assume k is always valid, 1 ≤ k ≤ number of unique elements. Given a non-empty array of integers, return the k most frequent
