Problem 45833. Triangle Numbers (★★)
(copy of problem 5)
Triangle numbers are the sums of successive integers. So 6 is a triangle number because
6 = 1 + 2 + 3
which can be displayed in a triangular shape like so
* * * * * *
Thus 6 = triangle(3). Given n, return t, the triangular number for n.
Example:
Input n = 4 Output t is 10
