So, the other day I was messing around with this “n-4” thing, and let me tell you, it was a bit of a journey. I started by, well, just trying to figure out what it even was.
I’d heard some folks talking about it, so I did some digging. Turns out, it’s related to how many, you know, steps you take back from a certain point. At least, that’s how I understood it. I’m no expert, just a guy who likes to tinker.
My Experiment
First, I picked a starting point. Let’s just call it ‘n’. I had this number in my head, and I decided I’d see what happened when I went four steps back. Easy enough, right?
- Step 1: Write down ‘n’. I actually grabbed a piece of paper and a pen for this. Old school, I know.
- Step 2: Subtract 1. Okay, still with me.
- Step 3: Subtract another 1. We’re at n-2 now.
- Step 4: Keep going! Subtract 1 again. n-3.
- Step 5: One more time. Subtract 1. Boom! n-4.
That seemed pretty straightforward. I mean, it’s just subtracting one four times. But I wanted to see if I could use this somehow.
Trying it out
I played around with different values for ‘n’. I put in, like, 10, then 25, even 100. Just to see what would happen. Each time, I followed my little five-step process and ended up four less than where I started. Amazing!
Then, for the fun I try to make it automatic, so I write some simple codes, input n is 10, then it ouputs 6. Just a simple try.
I did it!
Honestly, I’m still not 100% sure what all the fuss is about with this “n-4” thing. But it was kind of fun to play around with. Maybe it’s useful for something bigger, I don’t know. But for now, I’ve got my little experiment, and that’s good enough for me.
Any way, just thought i would share. It is not professional, just for some fun.
