sorting consecutive values

[Cainnech]

Hi everyone,

I have an array which has 7 values.
I would like to check if they are consecutive.

So this is the array:

my_array[0] = 2;
my_array[1] = 5;
my_array[2] = 6;
my_array[3] = 7;
my_array[4] = 8;
my_array[5] = 9;
my_array[6] = 13;

So I would like it to count how many consecutive numbers there are. In this case, it's 5 (5, 6, 7, 8, 9).

Anybody has any idea how to accomplish this?
Thanks.

loop through the array and increase a counter variable each time the value is consecutive to the previous/next one.

Based on your example, you will also need to keep a variable which checks the largest number of consecutive numbers, otherwise you'd only get 1 (the first one).

Alternatively, you could just check for one set of consecutive numbers, so if it's greater than one, it's a set.
