DAY 10 OF 90 · Count it

Triangular numbers

Easy90 Days of Looping

Inputs

n is a whole number from 0 to 15.

Create an empty list triangles and a number running that starts at 0.
Use a loop over the whole numbers 1 up to and including n. Add the loop number to running, then add the new value of running to triangles.
Complete triangularNumbers so it returns triangles. Return it, do not print it.

With n = 5, triangularNumbers returns [1, 3, 6, 10, 15].

TEST DATA 1: n is 5

TEST DATA 2: n is 0

Loops that count, add up and multiply. Every algorithm starts here: a counter, a total and a stopping point.
