![In this problem, we are working with binary strings with length K. A binary string
contains only characters '0' and '1'. The bitwise XOR of two such strings X and Y
(denoted by X OY)is also a binary string with length K.
You have a sequence A of binary strings, indexed from 1. Initially, it is empty.
You should process Q queries. In each query:
• You are given two integers L and R (0 < L< R< 2k ). For each i (
L<i<R), consider the string which is the binary representation of i,
possibly padded with leading zeros so its length is exactly K; append this
string to A. In total, you should append (R – L+ 1) strings to A in this
query.
• Then, compute the number of pairs (i, j) (1 < i < j<|A|) such that
(A¡ O Aj) is a palindrome. Since this number can be very large, compute it
modulo 998, 244, 353.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1eb128b6-4c6c-43f1-8060-e130da342117%2Fe9e483d1-4cd9-4b61-ac1f-960270f1cf11%2Fq1zo82i_processed.png&w=3840&q=75)
