Finally, spring weather showed up in Wellington this week. We cashed it as much as possible by going on treks, cycling trips, more treks and of course doing laundry.
Anyways, I don’t have time to blog. I must go out and help kids with some cycling. But I want to keep you busy this weekend. So here is a fun homework problem.
Does my range have all numbers from 1 to n?
Let’s say you have a range called range (duh!). And you want to check if range has all the numbers 1 to n (say n=5) in it, each number appearing only once (no more, no less). You can assume the named ranges range and n in your formulas.
See above examples to understand the problem.
So go ahead and post your formulas in the comments section. I will sneak in whenever I can to look at all your creative answers.Continue »
First a little back story:
Last Friday (on 29th of July), we (Jo, kids & I) went on a day walk to Red Rocks. It is a rugged coastal walk near Owhiro bay in Wellington. It was a windy & cold day. So why did we brave the elements of nature on this 10km walk? To see seals of course. And we did find a few of them. We also caught glimpses of snowy peaks in Southern Island of New Zealand.

Now I can’t take you on the same walk thru internet. There is no Excel function that can teleport you from your office (or home) to Owhiro bay. So I made the next best thing.
