PUUNTO LUUITE ded Program 3 3) Write a program named Full_Xmas Tree using a nested for loop that will generate the exact output. This program MUST use (ONLY) for loops to display the output below. For example the 1st row prints 1 star 2nd row prints 2, the 3rd row print 3 stars and so forth... This program is controlled by the user to input for the amount of row. "Prompt the user to enter the dimensions of the tree" A good test condition is the value of ten rows. (hint***)This program should account for white spaces print("* "). Remember the purpose of print() and println() Expected output: * Please enter the desired number of rows: 6
