Queries to count characters having odd frequency in a range [ L , R ] | Function to print the number of characters having odd frequencies for each query.
A function to construct the arr [ ] and prefix [ ].
Stores array length.
Stores the unique powers of 2 associated to each character.
Prefix array to store the XOR values from array elements.
