Hi guys !

I have a hash of arrays (the number of arrays is random and each array can hold different number of values), each array holds a list of numbers. The hash is built on runtime according to user's input from STDIN (each iteration builds one array), so far so good.
What I need is to verify that in each array the numbers are consecutive, all the arrays together should holds numbers from 0 to the higher number the user entered, and no number should appear more than once, for example:
Example 1:
(iteration 1): 0 1 2
(iteration 2): 4 6 5   

### Wrong input - missing 3, and second array is not consecutive

Example 2:
(iteration 1): 4 5 6
(iteration 2): 0 1 2 3 4

### Wrong - 4 appears twice

Example 3:
(iteration 1): 4 5 6 7 8
(iteration 2): 0 1 2 3

### this one is OK

In general, I can join all the arrays to a big one, sort it, and check that each array value equals the array's index, but I'll fall in case the user enters:
first:  0 1 3
second: 2 4 5

The joined array will qualify but the little ones not. anyone has a short idea (long solutions I have in plenty, but probably very ugly) ?

Thanks
