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.  \nIn 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.  \nCoding 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?  \nI think it’s helpful to divide coding interview questions into different topic areas. 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. string algorithm, sorting algorithms like quicksort or radix sort, and other miscellaneous ones), and that’s what you will find in this article.  \nIt’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.  \nOnce you have gone through these questions, you should feel  \nconfident enough to attend any telephonic or face-to-face interviews.  \nWithout any further ado, here is my list of some of the most frequently asked coding interview questions from programming job interviews:  \nArray Coding Interview Questions  \nAn array is the most fundamental data structure, which stores  \nelements at a contiguous memory location. It is also one of the darling  \n[https://simpleprogrammer.com/](https://simpleprogrammer.com/)  \ntopics of interviewers and you will hear a lot of questions about an array in any coding interview, e.g. reversing an array, sorting the array, or searching elements on the array.  \nThe 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.  \nIn 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 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.  \nHere are some of the popular array-based coding interview questions for your practice:  \n1. How do you find the missing number in a given integer array of  \n1 to 100?  \n2. How do you find the duplicate number on a given integer array?  \n3. How do you find the largest and smallest number in an unsorted integer array?  \n4. How do you find all pairs of an integer array whose sum is equal to a given number?  \n5. How do you find duplicate numbers in an array if it contains multiple duplicates?  \n6. How are duplicates removed from a given array in Java?  \n7. How is an integer array sorted in place using the quicksort algorithm?  \n8. How do you remove duplicates from an array in place?  \n9. How do you reverse an array in place in Java?  \n10. How are duplicates removed from an array without using any library?  \nReady for the solutions to the problems?  \n[https://simpleprogrammer.com/](https://simpleprogrammer.com/)  \nHere are the solutions to each of these array problems:  \n1. How do you find the missing number in a given integer array of  \n1 to 100? (solution)  \n2. How do you find the duplicate number on a given integer array?(solution)  \n3.
