][1]So last Friday, I posted a puzzle given to me by a colleague. You can see the puzzle here. I think that I was able to solve the puzzle using T-SQL, and Jamie has since informed me that I was right!!
Here’s the puzzle again just for reference:
John lives in a house that has the reverse numbering to Jane’s house (so, for example, if John lived at number 56, Jane would be at 65). The difference between their house number ends in 2. Neither John or Jane live in a house numbered between 1 and 10, nor in a house number over 99. What are their house numbers?
