### Example: A Triangle of Dollars

Write a program , which takes the number n and prints a triangle of dollars.

Input Output Input Output Input Output

4 $ $ $ $ 
 
5 $ $ $ $

#### Hints and Guidelines

The problem is similar to the draw a rectangle and square ones. We will use nested loops again, but there is a catch here. The difference is that the number of columns which we need to print depends on the row, on which we are and not on the input number n. From the example input and output data we see that the count of the dollars depends on which row we are on at the moment of the printing, i.e. 1 dollar means first row, 3 dollars mean third row and so on. Let's see the following example in detail. We see that the variable of the nested loop is connected with the variable of the outer. This way our program prints the triangle.
