To generate the specified pattern of letters and numbers efficiently, use a single loop rather than nested loops. The structure of the pattern indicates that letters A-H cycle every eight iterations while the number increments every eight letters. The pattern can be arranged directly by calculating the respective index for letters and numbers. Incorporating this into a simple loop will allow for the extension of the printing logic to handle more than 24 iterations as needed.
The key to generating the letter-number pattern involves understanding the sequence of letters A-H and how they repeat across numbers 1-3.
