Brain Teaser Index

These brain teasers are intended to illustrate useful and interesting computing techniques and software features.

Nearly all of them manipulate data in some way, and many of them require shuffling data back and forth between different applications.

Read the brain teasers and look at their data (if any). Cast your thoughts about and then try out ideas until a solution arises. Multiple solutions are possible, but elegance in the form of speed and simplicity trumps all.

To submit a solution, copy and paste the brain teaser into a word processing document and beneath it outline the steps to your solution and/or make any comments you'd like.

Print the document on one page and no more.

(It is not necessary to include solution data, but you may include an example of it as long as the entire solution fits on one sheet of paper.)
