Suppose you have an integer variable called size which has already been declared initialized to have a positive value. Write a code fragment uses nested for loops to print a grid of $s with size rows and size columns. For example, if size had the value 3, then your code should print the following pattern:

Your outer loop should loop size times, and your inner loop should also loop size times. You should print one $ each time through your inner loop.
