# The Quiz

## This Month: The Return of the Text Sudoku

This month we present another Sudoku puzzle with a twist—it uses letters instead of digits and hidden within it is the name of a kind of document sometimes written by software developers.

 X X X X O X I X T
 X F X M X A O X X
 X X X X X X M A E
 E M X N X X X X I
 N X X X A X X X T
 T X X X X F X M N
 F I A X X X X X X
 X X O S X F X E X
 N X S X I X X X X

Simply fill in the empty cells with the nine letters A, E, F, I, M, N, O, S, and T, so that each row, column, and small square contains each of the nine letters once.

# Answer to Last Month’s Quiz

Each of last month’s quotations had something to do with programming or computers. They were encrypted with a simple letter-substitution cipher, a different cipher for each quote. Punctuation and numerals were not encrypted, and each cryptoquote included at least one numeral.
