Sum of XOR of all subarrays | Function to calculate the Sum of XOR of all subarrays.
variable to store the final Sum.
multiplier.
variable to store number of sub - arrays with odd number of elements with ith bits starting from the first element to the end of the array.
variable to check the status of the odd - even count while calculating c_odd.
loop to calculate initial value of c_odd.
loop to iterate through all the elements of the array and update Sum.
updating the multiplier.
returning the Sum.
