So i wrote the code and ran it, and got the error saying "java.lang.NumberFormatException:, method main, line: 18" and "Error converting a string to a number (invalid format)." Thats what you get i think when you enter letters instead of number (Even though i entered the digit, not letter) and try to parse it. And got stuck for half hour trying to figure whats wrong with the code, and then i just tried to verify it as it is, and it passed?!?!? If you can please check if something is wrong with the task.
