Find the sum of MEX of all subarrays of the given array. The MEX (minimum excluded) of an array is the smallest non-negative integer that does not belong to the array. For instance: The MEX of [2,2,1] is 0, because 0 does not belong to the array. The MEX of [3,1,0,1] is 2, because 0 and 1 belong to the array, but 2 does not.
