Hi all,
I am working on a programming project and want to know how many possible combinations can exist in a particular situation, but I have no idea how to work it out. It isn't homework, I just want to know because I am sure it is a VERY large number and want to make a point.
There are 2 vectors, one vector is one dimensional and is, say, 5 in length with values in it: [ 1 | 2 | 3 | 4 | 5 ] and the second vector is two dimensional and empty (to be filled with the numbers in the one dimensional vector), say like so:
+---------+
| - | - | - |
| - | - | - |
| - | - | - |
+---------+
How would I go about working out working out how many combinations of those 5 numbers can be placed in the above two dimensional vector?
eg. one would be:
+---------+
| 1 | 2 | 3 |
| 4 | 5 | - |
| - | - | - |
+---------+
another:
+---------+
| 1 | 3 | 2 |
| 4 | 5 | - |
| - | - | - |
+---------+
Thank you for any help
