Answer 1

Tip: Don't count each single B
Get only the index of H and P
Subtract them. So you can get the number of block between them. To both sides!
Maybe you will need abs(difference).

Answer 2

I've solved it but in another way :D
Thank you very much for your help!

Answer 3

I've added this on the code but I forgot to modify here too. But I'm still getting error.

Answer 4

Ok, now you are only searching to the right. What will be happen, if the pod is on the left side?

Answer 5

Where are you using the "P" in your code. That's your target. So you have to take it into account.
