You can use loops to iterate over array.Here are some tips to solve array based coding problems:
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. 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, like reversing an array, sorting the array, or searching elements on the array. Without any further ado, here is my list of some of the most frequently asked coding interview questions from programming job interviews:Īn array is the most fundamental data structure, which stores elements at a contiguous memory location. Top 50 Algorithms and Coding Interview Questions In that case, you should take a good introductory course like Data Structures and Algorithms: Deep Dive Using Java to refresh your DS and algorithms skills. Once you have gone through these questions, you should feel confident enough to attend any telephonic or face-to-face interviews.ītw, there is no point in attempting these questions if you don't have sufficient knowledge of essential Data Structure and Algorithms or you have not touched them for ages. 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. The topic areas I've seen most often in interviews are array, linked list, string, binary tree, as well as questions from algorithms like string algorithm, sorting algorithms like quicksort or radix sort, and other miscellaneous ones), and that's what you will find in this article. 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 Job 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 d ata 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 Luxsoft, 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.
