Q1 · Matrix-based Coding · EASY
In a matrix coding system, letters are represented by two-digit codes. The first digit is the row number (0-4) and the second digit is the column number (5-9). The matrix is: Row/Col | 5 | 6 | 7 | 8 | 9 0 | A | B | C | D | E 1 | F | G | H | I | J 2 | K | L | M | N | O 3 | P | Q | R | S | T 4 | U | V | W | X | Y What is the code for the word 'CAT'?
