How do you find the missing number in a given integer array of 1 to 100?.Here are some of the popular array-based coding interview questions for your practice: The key to solving array-based questions is having a good knowledge of array data structure as well as basic programming constructors such as loop, recursion, and fundamental operators.
In order to create a shorter or longer array, you need to create a new array and copy all elements from old to new. The key benefit of an array data structure is that it offers fast O(1) search if you know the index, but adding and removing an element from an array is slow because you cannot change the size of the array once it’s created. reversing an array, sorting the array, or searching elements on the array. It is also one of the darling topics of interviewers and you will hear a lot of questions about an array in any coding interview, e.g. Without any further ado, here is my list of some of the most frequently asked coding interview questions from programming job interviews: Array Coding Interview QuestionsĪn array is the most fundamental data structure, which stores elements at a contiguous memory location. Once you have gone through these questions, you should feel confident enough to attend any telephonic or face-to-face interviews. It’s not guaranteed that you will be asked these coding or data structure and algorithmic questions, but they will give you enough of an idea of the kinds of questions you can expect in a real programming job interview. string algorithm, sorting algorithms like quicksort or radix sort, and other miscellaneous ones), and that’s what you will find in this article. The topic areas I’ve seen most often in interviews are array, linked list, string, binary tree, as well as questions from algorithms (e.g. I think it’s helpful to divide coding interview questions into different topic areas. In this article, I’ll share some frequently asked programming interview questions from different interviews for programmers at different levels of experience, from people who have just graduated from college to programmers with one to two years of experience.Ĭoding interviews are comprised mainly of data structure and algorithm-based questions as well as some of the logical questions such as, How do you swap two integers without using a temporary variable? There are a lot of computer science graduates and programmers applying for programming, coding, and software development roles at startups like Uber and Netflix big organizations like Amazon, Microsoft, and Google and service-based companies like Infosys or Luxoft, but many of them have no idea of what kind of programming interview questions to expect when you're applying for a job with these companies.
