Question
Number of extensions needed!
Newton has shifted to a new house and it came to his notice that there is only one socket in his house !!! Newton does a lot of experiments using electricity and wants at least B sockets in his house. Furthermore, he has an ample amount of extension cords and each extension has A sockets and takes one socket. In others words, an extension cord extends one socket into A sockets. You need to tell Newton how many extension cords will be required so that he can have at least B sockets.
