hi @guptadev354
you code is correct and its working fine but you can still optimize your code All you need to do is if the Character is an UpperCase then print a new Line otherwise simply print your character in any case. Another thing you need to handle is that you must not print a new Line if we encounter a UpperCase character in first line.
