**The Best of Creative Computing Volume 1 (published 1976)**

The next instruction is 1-L-1, which records a 1 in square 10, returns us to square 9 and indicates that the next instruction is on board 1. Because square 9 contains a 1, our instruction is 0-L-2 so we replace the 1 with a 0, move to square 8 and proceed to board 2 for the next instruction. The tablet now appears as: [image] WE’RE HERE And on we go. If you continue following these instructions until you reach STOP, the tablet will finally appear as: *** [image] When STOP is reached, the success of the effort is measured by the longest string of consecutive ones that appear on the tablet. In the example, the longest string contained but three ones. The Aedians problem was not to follow a particular instruction set, but to create one. Specifically, their leader would be the person who could write the series of instructions that would produce the longest finite sequence of consecutive ones. Since you've just seen the example used to introduce the problem to the young Aedians, you'll have to beat three consecutive ones before you're their new leader. If you generate an impressive series, be sure to send the instructions to Creative Computing. All worlds seem desperately in need of leaders and we'll gladly publish your name as a likely candidate.

He pocketed the money without examining it and spent a nickel on candy for his little boy. He then discovered the error and found he possessed exactly twice the amount of the check. If he had no money in his pocket before cashing the check, what was the exact amount of the check? One clue: Mr. Karbunkle earns less than $50 a week. Can you find the missing number for each diagram? You first have to figure the pattern which may be horizontal or vertical with a relationship between every number, every second or third number. You may have to add, subtract, multiply, divide, invert or do a combination of these things. Have fun! [image]A [image]B [image]C [image]D Send us your favorite puzzles for this column!! 177
