Case to hold the Loop Current Tester, and a bunch more Testers. If a user at a customer says they can't hear on a call occasionally, there's not much you can do about it. It's probably the long distance provider on one end or the other. If only a single user at a customer is complaining that they can't hear on a regular basis, an Amplified Handset will probably help that user.
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.
Anyone who is following programming questions must be familiar with these questions and also knows the answer for most of these but for new guys and even for intermediate it's worth refreshing it before going to any programming job interview e. 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. Also, StringBuilder is not synchronized like StringBuffer and that's why faster and should be used for temporary String manipulation. 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. For example, the array needs contiguous memory to store objects but the linked list doesn't need that.
It's difficult to add and remove elements in an array because you need to shift existing elements but that is very easy with a linked list, as you just need to change the pointer to accommodate them.
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.
It's written by an ex-Googler and it is one of the most comprehensive course to revise all important data structures like an array, linked list, binary tree etc. 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.Write a program in C to print odd numbers between 1 to using for loop.
Wap in C to print all odd numbers between 1 to N using while loop. Identifiers. Identifiers are sequences of characters used for naming variables, functions, new data types, and preprocessor macros. You can include letters, decimal digits, and the underscore character ‘_’ in identifiers.
The first character of an identifier cannot be a digit.
Beginners Java program to display odd numbers between 1 Chapter 3: Operators, Expressions, and Program Flow¶. The focus of this chapter is an in-depth look at each of the ways that we can evaluate code, and write meaningful blocks of conditional logic.
This solution is an alternative if the 3-digit numbers include numbers that start with 0 (if for example you are generating PIN codes), such as , , etc.
