VF automatic grouping problem, urgent! ! ! !

What is "automatic grouping" and is it random? I don't know much about competition grouping, so I answered according to my own ideas:

Establish a team table, and the fields include team number, team name, lottery number (numerical type), game number (numerical type), etc.

Generate a random number and write it into the lottery number:

Size ss( 16)

a=val(right(time()，2))

Rand (1)

For i= 1 to 16.

s=int(rand()* 10+ 1)

ss(i)=s

end

Use team tables

i= 1

scan

Replay the lottery number with ss(i)

i=i+ 1

End scan

* Index lottery numbers to generate matching numbers.

Lottery number label lottery number index

i= 1

J= 1

scan

If i= 1

Reschedule the session number with j

i=i+ 1

other

Reschedule the session number with j

J=J+ 1

i= 1

endif

End scan
