Who can help me make a program for random lottery number prediction?

It needs four categories.


First type: random digits 0-9 should randomly display three digits

Second type: random digits 0-9 should randomly display four digits

Third type: random numbers 1-31 should randomly display five digits

Fourth type: random numbers 1-43 should randomly display six digits

It should have a menu.
Selecting 1 shows 3 digits; after the digits appear, you can still choose 1, 2, 3, 4, 5, 0 and a new random number will appear.
Selecting 2 shows 4 digits; after the digits appear, you can still choose 1, 2, 3, 4, 5, 0 and a new random number will appear.
Selecting 3 shows 5 digits; after the digits appear, you can still choose 1, 2, 3, 4, 5, 0 and a new random number will appear.
Selecting 4 shows 6 digits; after the digits appear, you can still choose 1, 2, 3, 4, 5, 0 and a new random number will appear.
Selecting 5 shows all the numbers from 1 to 4; after the digits appear, you can still choose 1, 2, 3, 4, 5, 0 and a new random number will appear.
Selecting 0 exits.
