Mishmash Keypad

On Miu's smart phone, there is a search feature which lets her search for a contact name by typing digits on the keypad where each digit may correspond to any of the characters given below it. For example, to search for **TOM**, she can type **866** and for **MAX** she can type **629**. ```plain +------+-----+------+ | 1 | 2 | 3 | | | ABC | DEF | +------+-----+------+ | 4 | 5 | 6 | | GHI | JKL |
