Programming Enigma Puzzles

Posted by on **From New Scientist #1052, 26th May 1977** [link]

In this long division sum, I fear,

Most of the figures simply are not there.

Two and Three and Four and Six,

One of these is wrong. But which?

Three and Six and Four and Two,

Do you think that’s much too few?

Why don’t I give you rather more,

Than Six and Two and Three and Four?

To give you four, you will agree,

Is better than to give you three.

Look at the pattern if you wish.

All the figures look like this:Which figure was wrong? Find the correct division sum.

This completes the *Puzzle* series of puzzles that were originally published in *New Scientist* between May 1977 (when *Tantalizer* finished) and February 1979 (when *Enigma* started).

There is now a complete archive of puzzles from July 1975 up to December 1989, and from March 1998 to December 2013 (when *Enigma* finished). Making a grand total of around 1542 puzzles on the site (plus a few extra) – about 30 years worth!

I will continue posting *Enigma* puzzles on Monday and Friday, and *Tantalizer* puzzles on Wednesday.
