I know it's removing the duplicate values in an array

No, it isn't.

It is creating a hash called %count where the keys are the stringified values in the array @Clec_id and the values are the number of occurrences of each array value. Then it is printing the keys and values of that hash.

It may be true that keys %count contains the values of the original array with duplicates removed but not guaranteed. For instance, if the array contains references, they won't exist as keys in the hash; only their stringified representation will. Also, the keys of the hash are unlikely to be returned in the same order as the values of the array.
