Utility that encodes strings to a button phone notation.
Converts text into a sequence of keys that you press on a push-button telephone to type that text.
To type symbol a you press key with number 2 once. So, a is encoded as 2
To type e you press key 3 twice, so it's encoded as 33.
Similarly dog encodes as 36664. (d as 3, o as 666, g as 4).
If adjacent letters are encoded with a same digits, a + is inserted between them. For example, cat is encoded as 222+28.
Space is encoded as 1.
To encode numbers symbol # is inserted in front of them. For example, 345 is encoded as #3#4#5
