C# Interview Questions

The project is a .NET Core application that includes code samples for some of the most frequently asked interview questions.

Problems

• Given an array of n integers and a number k , perform k left rotations on the array.
• Print multiplication table of size nxn.
• Find the sum of contiguous subarray within a one-dimensional array of numbers which has the largest sum.
• Given n, complete the fibonacci function so it returns Fibonacci(n).
• Detect if a string is Palindrome.
• Given a string, find the longest subsequence consisting of a single character.
• Insert an int item in a sorted linkedlist so that list remains sorted.
• Remove duplicate ints from a sorted linkedlist.

Functions

• ArrayViewModel.LeftRotationByD
• ArrayViewModel.PrintMultiplicationTable
• ArrayViewModel.MaximumSumSubArray
• RecursionViewModel.Fibonacci
• StringViewModel.IsStringPalindrome
• StringViewModel.LongesConsecutiveCharacters
• LinkedListViewModel.InsertItemInSortedList
• LinkedListViewModel.RemoveDuplicatesFromSortedList

Code

• var array = ArrayViewModel.LeftRotationByD(new int[] { 1, 2, 3, 4, 5 }, 1);
• PrintMultiplicationTable(10);
• var result = ArrayViewModel.MaximumSumSubArray(new int[] { -2, -3, 4, -1, -2, 1, 5, -3 });
• var fib = RecursionViewModel.Fibonacci(3);
• var palindrome = StringViewModel.IsStringPalindrome("Savvas");
• var tuple = StringViewModel.LongesConsecutiveCharacters("AABCDDBBBEA");
• var sorted = LinkedListViewModel.InsertItemInSortedList(linkedlist, new LinkedListNode<int>(0));
• var removed = LinkedListViewModel.RemoveDuplicatesFromSortedList(linkedlist);
