Need to generate list of all possible combinations 1-10

[tannersarms]

Hello

I am quite sure this question will have been asked before, but I don't know how I would narrow my search enough to easily spot the exact type of question I am asking.

I have a Keysafe which is bolted to the wall and the combination has either been forgotten or changed by the last person to set it. Rather than spend $30 on buying a new one, not to mention the effort required remove the old one, I'd rather spend a few minutes trying all the possible combinations.

As far as I understand it, the "rules" on the keysafe are that the combination can be anywhere between 1 and 10 characters in length, and that duplication does not count. That is to say if I "set" the code as 1122, I could simply press 12 and unlock and it would open. For practicalities sake though, I only want to get a list of possible combinations with a length of four, and I don't mind if "invalid" combinations (i.e. 2244) appear in that list though it would be nice if possible to not have them appear.

Reading around on the internet suggests that there should be a total possible number of combinations amounting to 1,023, though I'm not sure how this was calculated.

Thanks you for any assistance.

I'm not too sure what keysafe you are using in the first place.
One thing I'm not sure of:
Range of the numbers for each character (0 - 9?)

Lastly, it's against the rules in this forum to help a person break into a secured program... but then again it's a physical safe which is kinda different???
What's ur say in this, mods?

Yes, the reference range is 0-9. It's a Supra Keysafe. I can take a picture of it from inside my property (and the box with the new one the other half wants me to put up in its place that I want to return to Amazon!)

If it can't be posted,that's OK, I found a site called mathsisfun.com that reckons there are 210 possible 4 digit combinations (assuming repetition isn't used and order isn't important).

Hi, there are more than 1023 combinations.

Since, order matters and there can be 1 - 10 characters to open the lock, there are
P(10, 1) + P(10, 2) + P(10 ,3) + ... + P(10, 10) which is...
9864100 combinations.

Do you really want to go through each one to open your lock?

oops. didn't realize you needed 4-digit strings :P (silly me, it was in your first post1)
Anyways, glad you found your solution.
