History[ edit ] From the beginning of computing, the sorting problem has attracted a great deal of research, perhaps due to the complexity of solving it efficiently despite its simple, familiar statement. Classification[ edit ] Sorting algorithms are often classified by:
Programming questions like reversing String using recursion or How to find if Array contains duplicates are some popular examples of programming question in Java. These programming interview questions are from my personal collections and I have only chosen those which are not very difficult, can be solved easily but at the same time can become too complex or confusing, present lots of follow-up questions and test fundamentals of programming, OOPS and design.
I have not given answers to these programming questions but those can be found by Google and I will try to post links of answers here sometime later but at the same time, I will try to provide quick tips or hints on some questions. String Programming Interview Questions The string is a primary and probably most common thing you come across on any programming language and so is with any programming interview.
There is almost always a question on String whether its related to length or replace but I have always found one or two String programming questions on interviews.
This can be done by using either StringBuffer reverse method or by technique demonstrated in the solution here. Couple of reasons which I think make sense is an implementation of String pool, Security, and Performance.
Java designers know that String will be used heavily in every single Java program, so they optimized it from the start. You can even use a regular expression to split a big string into several smaller strings.
If you can solve all these String questions without any help then you are in good shape.
If you need more practice, here is another list of 20 string coding questions. Programming questions on Array An array is one of the topics where most of the programming questions are asked. There are many and many programming questions on Array and here I have included only some of them which are not very difficult to solve but some of array programming question can be extremely challenging, so well prepare this topic.
Here is a quick tip to solve this programming question: If you need more advanced questions based upon array then you can see also see The Coding Interview Bootcamp: And, if you feel 10 is not enough questions and you need more practice, then you can also check out this list of 30 array questions.
It actually compliments array and whatever you cannot do with an array, you can do with a linked list. But, nothing is free in this world. While linked list provides all these functionalities but the cost of that you lose the ability to search elements in constant time with index.
Searching and element require traversing linked list, which means examining all nodes, thus cost around O n time.
To answer this programming question I would say you start with a simple solution on which you traverse the LinkedList until you find the tail of linked list where it points to null to find the length of the linked list and then reiterating till middle.
How do you find the start of the loop? Deep Dive Using Java course. Binary Tree Programming Interview Questions Binary tree or simply tree is one of favorite topic for most of the interviewer and pose a real challenge if you struggle with recursion. Programming questions on the tree can become increasingly difficult when you think iterative but sometimes can be very easy if you come with a recursive solution.
Programming Questions on Searching and Sorting I have only included two programming questions related to searching and sorting but there are more can be found on Google. Purpose of these programming questions is to see whether a programmer is familiar with the essential search and sort mechanism or not.
Both iterative and recursive? A good book to prepare for programming job interviews in a short time. General Programming Interview Questions In this category of programming questions, I have put questions which are not fit into any data structure but presents a real-life problem and you need to provide a solution.
These programming questions are sometimes based on problems faced by the developer itself. I have not included many Software design-related programming question which I have shared on Top 20 software design questions and answers ; you can also check that.
You can refer it to answer this question. Books to prepare for Programming Job Interviews There are a lot of good books available, which can help the programmer to do well on Interviews.
Here is a list of book, which I personally prefer, in the order, I like them.After sorting them like this..I advice that you write the code for cout.
