Using a while loop, write a Python program that asks the user to enter a number that is larger than 10. The program will continue asking for a number until a number that is larger than 10 has been entered. If the number entered, call it x, is less than 10, a message "x is too small by at least y" is printed, where y is the smallest number that must be added to x to make it greater than 10. If the number entered is equal to 10, a message "x is not greater than 10" is printed. If the number entered is greater than 10, a message "x is valid" is printed. Once a valid number is found, the program will print "Done".
