welcome to this post. Today I am going to talk about Searching Algorithms. In this tutorial, I will cover 3 Searching Algorithms Linear Search Binary Search Interpolation Search So Let start with Linear Search Linear Search: From the name, you can get an idea. It searches linearly. One by one. This algorithm starts the search from the beginning and continues until finding the desired search index. For example, Assume an array from 0 to 10. and you are searching for10. so what will happen? First,...

Welcome to this post. In this post, we are going to learn about the Circular queue. If you don't know the queue data structure, please check this post Queue. In the previous post of Queue, I discuss the problem about the queue. So today we learn about the circular queue. In queue, to data in the queue, the method is called enqueue()   and to get data from the queue, the...

Welcome to this post. This is the second post about data Structure. In this post, we are going to learn about Queue data structure. In the previous post, we discuss Stack. Stack is FILO type data structure. But Queue is the FIFO data structure, that means the data enter first that also come first. Src: Wikipedia In queue, to data in the queue, the method is called enqueue()   and...

Welcome to this post. This is going to be a series post about data structure and algorithm, In this series, I use kotlin as a default language. Let's start with stack data structure- Stack is a simple data structure. The implementation of this data structure is also called LIFO that means Last in Fast out. Basically, in this data structure, the last data will come in first. Src: Wikipedia In...

Hello visitors, After a long gap, I bring a post for you. I don't like to waste your time anymore. Let's start- Today, I will write about a new library. The Library is about for android theming and color plate. First of all, see some screenshot- So you can see that this library has an awesome theme list.

Welcome to kotlin Series In this post, we are going to discuss a very important topic of Kotlin. The topic is kotlin null safety. I think you already heard this keyword, null safety, Kotlin is a null safety language. right? what is the null safety? In kotlin by default, you can not assign a value of a variable as null. All the variable must have a value. but if you want an assign a variable as null, you have to use? code- val nullValue:String? = null if you want to create...

welcome to kotlin series. Kotlin Series In this series, we are basically going through some basic and advanced tutorial about kotlin language. we try to serve you best practices on those tutorials. Here is the collection of all post 1. String -  kotlin string tutorial 2. Array and loop - array and loop tutorial 3. File reader and write - kotlin...

Welcome to kotlin Series In the tutorial, we are going to discuss Kotlin collection. we touch on below topics 1. Hashmap 2. Array 3. List        3.a. mutable list        3.b. immutable list 4. Set        4.a. mutable set        4.b. immutable set Let's start- Hashmap: In kotlin, we can use java hashmap easily. But kotlin has an own hashmap. First, we go through Java hashmap create an instance of Hashmap class...

Welcome to kotlin Series In this small post, we are going to discuss how to control loop in Kotlin. Basically, we use 2 keywords for the control loop. 1. continue 2. break if we want to skip one process, then we use to continue the keyword for (a in 1..5){ if (a==4){ continue } println("A: $a") } Output: A: 1 A: 2 A: 3 A: 5 or if we stop the loop then we use break keyword for (a in 1..5){ if (a==4){ break } println("A: $a") } Output: A:...

Welcome to kotlin Series In this post, we are going to learn about ArrayList. In android the use of ArrayList is huge. So let's move on today task list. 1. we create an ArrayList 2. insert some value 3. update some value 4. search in ArrayList 5. delete some value Let's start: Note: we discuss array and loop in this post Kotlin: Array and Loop. you can take a look at this post of...
