Another one.. But Interesting.. Question: To Generate the non-repeated characters of String. Given two integers X and Y, returns containing exactly X letters "A" and exactly B letters "b". X defines maximum of character repetition. Input : Example: NonRepeatString(2,5,3); Output : AAbAAbAb Get the source code from GitHub

Fibonacci ... What's that?? Still most of interviewers favorite topic is from fibonacci series.. Formula :  Now the Question is Write a function that takes an array of integers as input. For each integer, output the next fibonacci number. Solution that work both cpu and memory efficient are appreciated. For example: nextFibonacci([1,22,9]) Output: 2 34 13 Answer : Get it from Github Gist If anybody knows some better solution these, please comment in this post.

Hi everyone, Have a great day. Again after long days, I post some interview question. Check below. If you've some best solution this, then you can comment on the post. Question: Write a function that takes two arrays as input, each array contains a list of A-Z; Your program should return True if the 2nd array is a subset of 1st array, or False if not. For example: isSubset([A,B,C,D,E], [A,E,D]) = true isSubset([A,B,C,D,E], [A,D,Z]) = false isSubset([A,D,E], [A,A,D,E]) = true Answer : See my Github Gist .

Hi friends, Have a great day. Today I just upload the sample shopping list application using firebase. You can view and download it from the Github . Now most of developers start using firebase, It's very easy and very comfortable. Try it yourself. It's have a lots of features.

Wish you happy new year 2019 to everyone. Yeah It's new beginning. Let's do fresh start with Kotlin. Kotlin introduced by Jetbrains, the offical designer of the most intelligent Java IDE named Intellij IDEA. In 2017, Google announced Kotlin is an offical language that runs on JVM. Why Kotlin? Kotlin is an open source programming language that combines object oriented programming and functional features into a unique platform. Kotlin is 100% inter-operable with java. Kotlin compiles to JVM bytecode or Javascript. Kotlin costs nothing to adopt. It imposes to runtime overhead. Features: Kotlin is null safety. It's lean syntax. Exceptions are unchecked. Functional Programming Distinguishes between mutable and immutable views over collections. Have an operator overloading. Extension functions let you add methods to class without modifying their source code. Delegation can be done automatically. No more boilerplate's. Less code, more clean...
