Effective Go Introduction Go is a new language. Although it borrows ideas from existing languages, it has unusual properties that make effective Go programs different in character from programs written in its relatives.

Top 50 Java Programs from Coding Interviews Coding is an integral part of any programming job interviews Java development interviews are no exception.

I would even suggest you should never hire anyone without testing their coding skillcoding is also an art and more often than a good code is a good developer as well. If you look at tech giants like Amazon, Facebook, and Google they thoroughly test the coding skill of any developer they hire, particularly Amazon who first send online coding exercises to filter Java programmers who can code.

This online test usually gives you requirements and ask you write a program in limited time usually 2 to 3 hours.

The program should meet the output given by the exercise itself. Btw, the most important question is how do you develop that kind of coding skill in the first place? Well, things always start small and if you pay attention, there are many Java Job interviews where you would have been asked to write small programs.

They are simple but yet they give a good indication of coding skill of perspective candidates. They are usually preferred by many companies because it usually requires 10 to 20 minutes to write the solution and discuss them.

In this list, I am going to share 50 of such small programs from Java Programming interviews. These programs are from various Data Structure and Algorithm topics e. Introduction to Algorithms by Thomas H. If you find that book difficult, you can get more options in my post about algorithm books here.

As I said it includes questions from problem-solving, linked list, array, string, matrix, bitwise operators and other miscellaneous parts of programming. Once you gone through these questions, you can handle a good number of questions on real Job interviews.

Fibonacci series solution Write a simple Java program which will print Fibonacci series e.

Top 10 Java Programming Coding Interview Questions Answers for programmers | Java67

Be prepare for cross questions like using iteration over recursion and how to optimize the solution using caching and memoization. Prime number solution Write a Java program to check if a given number is prime or not.

Remember, a prime number is a number which is not divisible by any other number e. Be prepared for cross e. String Palindrome solution You need to write a simple Java program to check if a given String is palindrome or not. A Palindrome is a String which is equal to the reverse of itself e.

Though be prepared with both recursive and iterative solution of this problem. The interviewer may ask you to solve without using any library method e. Integer Palindrome solution This is generally asked as follow-up or alternative of the previous program.

This time you need to check if given Integer is palindrome or not. An integer is called palindrome if its equal to its reverse e. You can use divide by 10 to reduce the number and modulus 10 to get the last digit.

This trick is used to solve this problem. Armstrong number solution A number is called an Armstrong number if it is equal to the cube of its each digit. You need to write a program to check if given number is Armstrong number or not. Avoiding deadlock in Java solution This is one of the interesting programs from Java Interviews, mostly asked to 2 to 3 years of experienced programmers or higher.

Interviewer simply asked you to write code where a resource is accessed by multiple threads.

You need to write code in such a way that no deadlock should occur. The trick to solving this problem is acquiring resources in an order and release them in reverse order e. This way you can avoid deadlock. Factorial solution This is one of the simplest programs you can expect on interviews.

It is generally asked to see if you can code or not. Sometimes interviewer may also ask about changing a recursive solution to iterative one or vice-versa. Reverse a String solution This problem is similar to the String Palindrome problem we have discussed above.

If you can solve that problem you can solve this as well. You can use indexOf or substring to reverse a String or alternatively, convert the problem to reverse an array by operating on character array instead of String.Merge sort runs in O (n log n) running time.

Java; Table of Content. C Program to Implement Insertion Sort in C Programming; C Program to Sort Structures on the basis of Structure Element; C Program to Implement Bubble Sort in C Programming; C Program to Sort the list of Strings; C Program to Sort array of Structure;. In this tutorial we will see how to sort an ArrayList of Objects by property using comparable and comparator interface. If you are looking for sorting a simple ArrayList of String or Integer then you can refer the following tutorials –. Sorting of ArrayList and ArrayList Sorting of ArrayList in descending order. QUICK SORT USING C PROGRAM Source code of simple quick sort implementation using array ascending order in c programming language. #include void quicksort(int [10], int, int); int main(){ Write a c program for heap sort. 6. Write a c program for merge sort. 7. Write a c program for shell sort.

It is very efficient sorting algorithm with near optimal number of comparison. Recursive algorithm used for merge sort comes under the category of divide and conquer technique.

An array of n elements is split around its center producing two smaller arrays. Need to implement a quick sort program in r-bridal.coming the requirements. Attachment 1; appreciation for the parameters to be considered in selecting an appropriate sort.

4 Ways to Write Your First Program in Java - wikiHow

Write a Quicksort and a Natural Merge Sort. They should both be recursive or both be iterative, so that the overhead of recursion will not be a factor in your. To sort an array using insertion sort technique in C++ programming, you have to ask to the user to enter the array size and array elements in random order, now start sorting the elements of the array in ascending order using insertion sort technique as shown here in the following program.
