Without other details we need to find if there are two equal numbers(map (number -> number counter)). If this is the case we found two subarrays of length 1.

We can use Rabin Karp algorithm and generate hash for each possible sub-string using rolling hash. Using rolling hash reduces the complexity of generating hash since we will be reusing hash value of previous substring.

Add these to a map<hash, <start_index, length>>. So if we find to substrings with same hash and length then compare them. If they are equal then we have solution.

Create a map for each element in the array. if all values are even for all keys in the map then yes array can be divided into 2 subarrays.
