Example text

Either joker has a value of 53. When the cards must represent a letter, club and diamond values are taken to be the number of the letter (1 to 26), as are heart and spade values after subtracting 26 from their value (27 to 52 drops to 1 to 26). Jokers are never used as letters. Now let’s make sense of all that by putting it to use: 1. Key the deck. This is the critical step in the actual operation of the cipher and the heart of its security. There are many methods to go about this, such as shuffling a deck and then arranging the receiving deck in the same order or tracking a bridge column in the paper and using that to order the cards.

So, for example, a sample (eclectic) Barrel of Monkeys playlist might be as follows: 1. “Peace Train” 2. “No More ‘I Love You’s”’ 3. “Super Trooper” 4. “Rock Me, Amadeus” 5. “Song of the South” 6. “Hooked on a Feeling” 7. “Go Tell It on the Mountain” See how each song name begins with the last letter of the name of the song before it? Just creating any playlist would be too easy, however. We need a worthy problem to solve: 1. Given any starting and ending song, create a playlist that connects the two songs.

For more extra credit, try to find the shortest playlist that links the songs (either in terms of number of songs or total play time). Report erratum 48 Q UIZ 20. gz (100KB compressed). The song durations are in milliseconds. Finally, because this problem may be enough fun without having to discover trouble yourself, I offer a few things to think about here: • What do you do with songs with names like “’74-’75” or “Seventy Times 7” or “=:0 :(”? • How about a song named “Candy Everybody Wants (unplugged)” or “Voulez-Vous [Extended Remix, 1979 US Promo]” or “Speed Racer - Hardcore Mix” or “Breathe Remix Feat Sean Paul”?
