Foundations Loops through pattern printing
6. Right Triangle of Stars
Easy
Given an integer n, return the pattern below as a list of strings, one string per row, top row first.
The pattern has n rows. Counting rows from 1 at the top, row i holds i stars (*) side by side, with
nothing between them. Every row starts at the left edge, so the right side of the triangle forms a slope.
For n = 5 the pattern is:
*
**
***
****
*****
No row has a space at the end.
Example 1
Input: n = 4
Output:
* ** *** ****
Example 2
Input: n = 1
Output:
*Example 3
Input: n = 7
Output:
* ** *** **** ***** ****** *******
