@MayankMaheshwari is correct and their answer deserves your approval.
I'd just like to add that you are very, very close to finishing this Problem Set and should be proud of the work you have done so far.
One of the most important things you will learn in CS50, beyond just the ability to devise and implement algorithms, is attention to detail!
That blank space character in your output is almost invisible -- but there it is, starting you in the face.
Now go fix that bug, and click the green check mark to accept the most helpful answer (not mine!)
