Considering this, what are all the possible combinations of 1234?

If you wager on 1234 boxed, you would win ifanyof the following combinations were drawn: 1234,1243,1324, 1342, 1423, 1432, 2134, 2143, 2314, 2341, 2413, 2431,3124,3142, 3214, 3241, 3412, 3421, 4123, 4132, 4213, 4231, 4312,or4321.

Similarly, how many combinations are there for a 3 digit lock? Depends on the numbering system.Withbase 10 (i.e. zero to nine), there would be 10 x 10 x 10 =1000combinations. A brute force attack can simply be usedtofind combination.

Beside this, how many combinations are there in a 5 digit lock?
