You are now the lucky franchise owner of 'SpeedDating Inc'.
We are the number one organiser of speed-dating events in WhereverYouAre.
We would love for you to start organizing new events in your town, we think it certainly has potential.
And with the advent of pride month, we are doing a 'rainbow special'.
Normally, you would organise a heterosexual speed-dating evening as follows:
- Provide a numbered placeholder to each table.
- Ask all the ladies to be seated at their table
- Every turn, ask the men to go to the table that is one higher than their current number (except for whoever is sitting at the highest numbered table, they will move to table 1)
This system guarantees that all men will see all the women. And above all, it's very easy to explain. After all, these men will be here all evening, drinking some beers in between. You do not want complicated 'move to' rules.
Now, for rainbow events we've hit a bit of a snag.
If you use the same system as for the heterosexual people, half the men (for instance those doing the moving around) will never see half the men.
Your job is to figure out an easy to explain system, that will enable same-sex speed-dating.
