CodeChefOpen on judge ↗

The beauty of any sequence of integers in the BitLand is defined as the product of the number of integers in the list and the Bitwise XOR of those integers. Our little Chef Chang liked this way of defining the beauty of a sequence and henceforth, came up with the following puzzle. Find out how many sequences of non-negative integers of length N exist such that the sum of beauty values of all thei
