Hi,
I need some tips (idea) for creating software to generate
raffle tickets.
These are conditions:
1) Numbers from 1 to 90 must be allocated in 6 grids.
Each grid has 9 rows and 3 columns.
2) Every grid has 12 blank fields: 4 in each row, but every
column must have at least one number.
(in one row there must be 5 numbers and 4 blank fields)
3) At the end of one ticket (it has 6 grids - 6 raffle tickets) there must be
exactly
90 different numbers (from 1 to 90) with 72 blank fields.
4) Numbers in every column must be sorted. It can hold number, than
blank field and number again. It doesn't matter.
Like this (this is one grid - one raffle):
-------------------------------------------------------------------
| 1 | | 20 | 33 | | | 66 | 73 | |
-------------------------------------------------------------------
| | 13 | 25 | 39 | | 55 | | 74 | |
-------------------------------------------------------------------
| 5 | | | | 40 | 57 | 68 | | 90 |
-------------------------------------------------------------------
5) I have 4 sets of numbers that must fill in these grids.
In one set there are 6 numbers and these numbers must be
allocated in 6 grids. One in each grid. Whole 4 sets must
fit in 6 grids.
6) First column in each grid has numbers fro 1 to 9
Second from 10 to 19
Third from 20 to 29
...
Eight from 70 to 79
Ninth from 80 to 90
I just need some tips, but code or link would be nice.
I have code to random generate 90 different numbers, but I
have no idea how to allocate with conditions described above.
Thanks.
P.S.
I dont speak English very well. I hope you will understand.
