Use nested for loops to solve this program. 3. Ask the user for a number of rows and then use a while loop to validate to make sure the number of rows is greater than or equal to 2. 4. Print dollar signs in the shape of a tree (more like a Christmas tree) with the number of rows being equal to the number the user entered in. Refer to sample output for an example. HINT: You will have three for-loops in total to accomplish this. One outer for loop and two which are inside of the outer one.

sample output
