The challenge for this month’s Exercise is to count in “alphabedecimal,” generating output from AAAA through ZZZZ, without using nested loops or a complex if structure. Your solution must use a recursive function that handles flipping the digits, er, characters.

For this month’s Exercise, my solution to the scramble() function requires a second array. You could code a scramble() function without using a second array (or storage buffer), swapping individual characters within the string, but I chose not to.

The challenge for this month’s Exercise is to determine the greatest price gain for a stock during the trading day. The gain is calculated moving forward in time, from a low to a high. It’s easy to see with human eyeballs looking at a chart, but not so easy when you must code a solution.

I hope you had a wee bit of a struggle with your solution to this month’s Exercise. It involves a lot of decisions and proper steps in the right order to hold off on debits so that the bank account never dips below zero.

Your challenge for this month’s Exercise is to write a sign() function, which returns 1, 0, or -1 depending on the sign of an integer. A relatively simple thing to code — I hope!

The challenge for this month’s Exercise is to initialize two different arrays to two sets of values. You should try to use only one loop and try to use a single statement to make the element assignments.
