Jon Marius shouted too much at the recent Justin Bieber concert, and now needs to go to the doctor because of his sore throat. The doctor’s instructions are to say “aaah”. Unfortunately, the doctors sometimes need Jon Marius to say “aaah” for a while, which Jon Marius has never been good at. Each doctor requires a certain level of “aah” – some require “aaaaaah”, while others can actually diagnose his throat with just an “h”. (They often diagnose wrongly, but that is beyond the scope of this problem.) Since Jon Marius does not want to go to a doctor and have his time wasted, he wants to compare how long he manages to hold the “aaah” with the doctor’s requirements. (After all, who wants to be all like “aaah” when the doctor wants you to go “aaaaaah”?)

Each day Jon Marius calls up a different doctor and asks them how long his “aaah” has to be. Find out if Jon Marius would waste his time going to the given doctor.

Your Program

Write a program which asks the user for two strings:

  1. The "aaah" Jon Marius is able to say.
  2. The "aaah" the doctor wants to hear.

You may assume that the user will only enter lowercase a's followed by a lowercase h for each input.

Then, your program should determine wether Jon Marius can visit that doctor, and let the user know yes or no.

Example Interaction 1

Jon, say aaah: aaaah
Doctor wants to hear: aaaaaaah
No, Jon should not visit this doctor.

Example Interaction 2

Jon, say aaah: aah
Doctor wants to hear: aah
Yes, Jon should visit this doctor.

Example Interaction 3

Jon, say aaah: aah
Doctor wants to hear: h
Yes, Jon should visit this doctor.
