[백준/BOJ/C++] 7595번 Triangles

[문제]

It is not hard to draw a triangle of stars of any given size. For example, a size 5 triangle would look like this (5 stars high and 5 stars wide):

*
**
***
****
*****

Your task is to draw triangles in a number of sizes.

[입력]

Each line of input contains a single positive integer, n, 1 <= n <= 100. The last line of input contains 0. For each non-zero number, draw a triangle of that size. 

[출력]

Output consists of triangles of the appropriate sizes. Each triangle is wider at the bottom. There are no gaps between the triangles.
