Introduction To Algorithm

The word Algorithm means “a process or set of rules to be followed in calculations or other problem-solving operations”. Therefore Algorithm refers to a set of rules/instructions that step-by-step define how a work is to be executed upon in order to get the expected results. 

Advantages of Algorithms:

  • It is easy to understand.
  • Algorithm is a step-wise representation of a solution to a given problem.
  • In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program.

About Tutorial Challenges
Many of the challenges on HackerRank are difficult and assume that you already know the relevant algorithms. These tutorial challenges are different. They break down algorithmic concepts into smaller challenges so that you can learn the algorithm by solving them. They are intended for those who already know some programming, however. You could be a student majoring in computer science, a self-taught programmer, or an experienced developer who wants an active algorithms review. Here’s a great place to learn by doing!

The first series of challenges covers sorting. They are listed below:

Tutorial Challenges – Sorting

Insertion Sort challenges

Quicksort challenges

Counting sort challenges

There will also be some challenges where you’ll get to apply what you’ve learned using the completed algorithms.

About the Challenges
Each challenge will describe a scenario and you will code a solution. As you progress through the challenges, you will learn some important concepts in algorithms. In each challenge, you will receive input on STDIN and you will need to print the correct output to STDOUT.

There may be time limits that will force you to make your code efficient. If you receive a “Terminated due to time out” message when you submit your solution, you’ll need to reconsider your method. If you want to test your code locally, each test case can be downloaded, inputs and expected results, using hackos. You earn hackos as you solve challenges, and you can spend them on these tests.

For many challenges, helper methods (like an array) will be provided for you to process the input into a useful format. You can use these methods to get started with your program, or you can write your own input methods if you want. Your code just needs to print the right output to each test case.

Sample Challenge
This is a simple challenge to get things started. Given a sorted array () and a number (), can you print the index location of  in the array?

Example

Return  for a zero-based index array.

If you are going to use the provided code for I/O, this next section is for you.

Function Description

Complete the introTutorial function in the editor below. It must return an integer representing the zero-based index of .

introTutorial has the following parameter(s):

  • int arr[n]: a sorted array of integers
  • int V: an integer to search for

Returns

  • int: the index of  in 

The next section describes the input format. You can often skip it, if you are using included methods or code stubs.

Input Format

The first line contains an integer, , a value to search for.
The next line contains an integer, , the size of . The last line contains  space-separated integers, each a value of  where .

The next section describes the constraints and ranges of the input. You should check this section to know the range of the input.

Constraints

  •  will occur in  exactly once.

This “sample” shows the first input test case. It is often useful to go through the sample to understand a challenge.

Sample Input 0

STDIN           Function
-----           --------
4               V = 4
6               arr[] size n = 6 (not passed, see function description parameters)
1 4 5 7 9 12    arr = [1, 4, 5, 7, 9, 12]

Sample Output 0

1

Explanation 0
. The value  is the  element in the array. Its index is  since the array indices start from  (see array definition under Input Format).

  9. Of course, to play popular Bitcoin slots you will need to have a crypto wallet, which will be used to make deposits into the casino. The minimum deposit amount in each Bitcoin casino does not exceed 1 USDT or 0.0002 BTC. However, there are no limits for withdrawals. This significantly increases the popularity of cryptocurrency games. These are just some of the things we think about when reviewing crypto casinos for bitcoin gamblers. You can find out what else we look for by checking out our reviews of Yeti Casino and Fun Casino at the end of this page.  ⚠️ That being said, watch out for Bitcoin casinos which take a portion of your deposit or withdrawal for any reason. As you can see, using Bitcoin should never cost you, and so these casinos are simply trying to make money. Our advice would be to avoid these casinos at all costs. After all, you can simply find a better site to play at, where no such fees exist.

    La plupart des sites de casino pour l’argent prennent en charge les transactions avec les cartes de crédit et de débit Visa. Les joueurs peuvent effectuer des paiements rapides et sécurisés sans avoir à transférer de l’argent via un service supplémentaire. Par conséquent, s’il n’y a pas d’argent liquide sur votre compte bancaire, vous ne pouvez pas effectuer de dépôt. Vous pouvez également utiliser une carte prépayée qui limite vos dépenses. Stake propose également une plateforme de paris en direct, permettant aux parieurs de placer des paris pendant que les événements sportifs se déroulent en temps réel. Les paris en direct ajoutent un niveau d’excitation supplémentaire aux paris sportifs, car les parieurs peuvent ajuster leurs paris en fonction de l’évolution des événements sportifs. De plus, Stake offre une large gamme d’options de paris en direct, telles que les paris sur le score, les paris sur le vainqueur ou les paris sur les événements spécifiques d’un match.
