Draw the triangle 1 hackerrank solution

Query the average population for all cities in CITYrounded down to the nearest integer. Note : CITY. Code are matching key columns.

Another really interesting SQL Hackerrank problem, which forces you to break down a problem and build a procedure. While I know there are multiple ways to handle this problem like most , I feel like this way allows you to flex multiple skills and try out some different functions. P R represents a pattern drawn by Julia in R rows. The following pattern represents P 5 :. As stated before, I built out a procedure which called stars which executes when called.

.

Output one of the following for each node:.

.

It takes one parameter i, which will represent the number of rows in our triangle. This will form one row of the triangle. This step is important because it helps us move towards the apex of the triangle, reducing the number of stars in each row. In summary, this code defines a stored procedure that draws a triangular pattern of stars by looping through rows and decreasing the number of stars in each subsequent row until reaching the apex of the triangle. You can call this procedure with different values of i to draw triangles of varying heights. Your email address will not be published.

You need to know the inner workings of how SQL procedures work, which can easily be learned by watching some tutorials on Youtube, or learning SQL on Udemy. If you wanted to could just print out a bunch of stars. Not very clean or reusable code though. Therefore, I used 5 major components to solve this question, so that it could be done programmatically for any number inputted.
