Xor Counting
Find the number of sequences with $K$ elements which satisfy the following conditions: - Each element is an integer between $L$ and $R$ inclusive. - The bitwise XOR of all elements is between $A$ and $B$ inclusive. Since the number of sequences satisfying the given conditions can be quite large, compute it modulo $998,244,353$. ### Input - The first line of the input contains a single i
