Fun and Games with NSA
by Miki Saxon
The Federal government is definitely out of favor, whether for doing too little or too much depends on your MAP (it never does enough for us and does too much for them).
In no part of the government is this more obvious than NSA; the poster child of dislike, distrust and disdain.
But those feelings should hold only for the leadership, not the techies who staff the place.
NSA hires a lot of techies and techies are techies the world over. One of the things they all have in common is that they love puzzles, especially math and logic puzzles—not just to work them, but to create them.
“Intelligence. It’s the ability to think abstractly. Challenge the unknown. Solve the impossible. NSA employees work on some of the world’s most demanding and exhilarating high-tech engineering challenges. Applying complex algorithms and expressing difficult cryptographic problems in terms of mathematics is part of the work NSA employees do every day.”
So if you love puzzles click the link above and try your skills. Here’s a sample from a software developer.
Four friends, Holly, Belle, Carol, and Nick, gather for May birthdays. Holly announces that she has a game before dinner. She hid gifts for each of her friends inside three separate boxes secured with padlocks. She challenges her friends to figure out the combination without consulting each other.
She provides the following information. All the padlocks have the same combination. The padlocks use 3 digits from 0 to 9. She also tells them that the sum of the three digits is equal to nine, and every digit is equal to or greater than the previous digit. Holly tells each of her friends one of the digits in the combination. She states, “I’ve given the first digit to Belle, the second digit to Carol, and the third digit to Nick.” The caveat is that the friends cannot share their numbers with each other or they will forfeit the gifts.
Then Holly gives her friends 30 minutes to open the padlocks while she watches and finishes dinner.
The three friends begin to think of the solution. One by one, they each try their hand at their padlock, but none of them opens the padlock. Seeing that no one has succeeded, suddenly Carol realizes she knows the answer, and successfully opens her box, revealing a new fitness tracker. Following this, Nick opens his padlock, revealing a new tablet; and Belle opens her box to find new pair of headphones.
Having watched this entire event unfold, can you determine the correct combination?
Hint: Belle knows her digit is a 1.

Have fun, everybody.
