What is T9 / Phone Keypad Input?

T9 (Text on 9 keys) is a predictive text input method used on mobile phones with numeric keypads. Before smartphones with touchscreens, people used number keys to type letters by pressing each key multiple times.

For example, to type the letter 'C', you would press the '2' key three times (since 2 = ABC). To type 'HELLO', you would press: 44 33 555 555 666

How It Works:

  • Each number key (2-9) represents 3-4 letters
  • Press a key once for the first letter, twice for the second, etc.
  • Key 7 has 4 letters (PQRS), key 9 has 4 letters (WXYZ)
  • Multiple presses of the same key create different letters

Examples

Example 1: Simple Word

HI44 444

H = press 4 twice, I = press 4 three times

Example 2: Full Word

HELLO44 33 555 555 666

Example 3: Word with S

SOS7777 666 7777

S = press 7 four times (PQRS)

Example 4: Decoding
