The sum of the angles in a triangle is 180, and the sum of the angles in a square is 360. In fact, the sum of angles in any polygon increases by 180 with each side added to the polygon. In this problem, you must figure out the sum of angles of a polygon, given its number of sides.
Input
The first line of the input contains a positive integer T indicating the number of test cases in the problem. The next T lines each contain a positive integer n (1 <= n <= 100): the number of sides of each polygon.
Output
Output T integers: the sum of the angles in each polygon.

Hey everyone 😊, Today I want to share another interesting thing which I found in StackOverflow and that is how to pass parameters in webhook. Those who don't know about webhook I advise you to google about it before going further reading.  So for demonstration purpose, I am going to use Jenkins and Generic Webhook plugin . I created a job and called it testing  and select Generic Webhook  Trigger . Thereafter I add Request Parameter   and in the request parameter I added the name of the request which is name Thereafter I added a token to specify that this job can only be triggered. After this, I select Execute Shell from Build  and write the following code  After doing this add webhook URL in bitbucket repository or  GitHub repository with the parameter. The URL is look something like this  Webhook URL:- https://[YOUR_JENKINS_URL]/generic-webhook-trigger/invoke?token=trigger&name=Svastikkka  The configuration will something like this After saving my webhook configuration I

Hi everyone 😎 , Today we are going to see how to access or modify WikiJS resources using WikiJS API. WikiJS exposes GraphQL API to access and modify the stuff according to our requirements. So In this blog post, we going to see  How to set up WikiJS's local environment using docker. How to generate an API token in Wikijs. Using API tokens how to access WikiJS resources and how to modify them. First Local Setup using docker Here I am using docker to set up my local isolated WikiJS environment. Below is my docker-compose.yml file written by WikiJS contributors. To build the WikiJS environment we just need to run the following command  docker-compose up -df  [PATH_OF_DOCKER_COMPOSE_YML_FILE] To check the environment is in a running state run the following command docker ps Second Generate API token After setup our local environment we are ready to create our initial Administrator account in our WikiJS. 1. On the browser type localhost:80 2. Create an Administrator account  Email: loc

Fahrenheit to Celsius

-
Level EASY Given three values - Start Fahrenheit Value (S), End Fahrenheit value (E) and Step Size (W), you need to convert all Fahrenheit values from Start to End at the gap of W, into their corresponding Celsius values and print the table. Input Format : 3 integers - S, E and W respectively Output Format : Fahrenheit to Celsius conversion table. One line for every Fahrenheit and corresponding Celsius value. On Fahrenheit value and its corresponding Celsius value should be separate by tab ("\t") Constraints : 0 <= S <= 80 S <= E <= 900 0 <= W <= 40 Sample Input 1: 0 100 20 Sample Output 1: 0 -17 20 -6 40 4 60 15 80 26 100 37 Sample Input 2: 20 119 13 Sample Output 2: 20 -6 33 0 46 7 59 15 72 22 85 29 98 36 111 43 Explanation For Input 2: We need need to start calculating the Celsius values for each of the Fahrenheit Value which starts from 20. So starting from 20 which is the given Fahrenheit start
