Merging Arrays – Solution
This month’s Exercise is about coding a merge() function, which swallows two arrays and generates a third as output. The new array is “zippered” from the original arrays, alternating values from each.

A Compact for Loop – Solution
I hope you were able to cram a lot of expressions into a for loop statement, which is the challenge for this month’s Exercise. Even if you know this trick, it’s important to understand it’s limitations — which is something I discovered during my research.

Output a Colorful Chessboard – Solution
This month’s Exercise may not seem that difficult, especially given the variety of grid challenges and dimensional array lessons I’ve posted on this blog. Obviously, you need a nested loop. The tough part, however, is generating the grid of alternating colors.

Palindromic Numbers – Solution
The challenge for this month’s Exercise is to output the first 100 palindromic numbers, which are integers that reflect the same digits on either side. Rather than devise a complex mathematical equation to determine these values, I cheated.

Cyclops Numbers – Solution
I hope this month’s Exercise didn’t terrify you. I remember seeing The Seventh Voyage of Sinbad when I was a kid. The cyclops bothered me so much I asked my mom questions about him for a month.
