write two functions: insertNode and forwardTraverse, for an XOR linkedlist, a.k.a, memory efficient doubly linked list (DLL) in C PL. Ordinary DLLs requires space for two addresses(one pointing to previous node and one to next node). However, XOR LLs use bitwise XOR operation tosave space for one address. Consider the below ordinary DLL.

The Burrows-Wheeler transform (BWT) is a transformation that is used in data compression algorithms, including bzip2, and in high-throughput sequencing in genomics. Write a SuffixArray client that computes the BWT in linear time, as follows: Given a string of length N (terminated by a special end-of-file character $ that is smaller than any other character), consider the N-by-N matrix in which each row contains a different cyclic rotation of the original text string. Sort the rows lexicographically. The Burrows-Wheeler transform is the rightmost column in the sorted matrix. For example, the BWT of Mississippi is ipssm$pissii. The Burrows-Wheeler inverse transform (BWI) inverts the BWT. For example, the BWI of ipssm$pissii is mississippi$. Also write a client that, given the BWT of a text string, computes the BWI in linear time.

Design a TM to accept {a^ib^j | i<j}. Justify your design with an example
Define a function named get_sorted_in_parallel (tuples1, tuples 2) which takes two tuples of integers as parameters. The tuples have the same length and their elements are related, i.e. the element at each index of the second parameter tuple corresponds to the element at the same index in the first parameter tuple, e.g. the element at index 1 in the first tuple corresponds to the element at index 1 in the second tuple. The function sorts the first parameter tuple, keeping the elements of the second parameter tuple in the order corresponding to the sorted first parameter tuple. The function returns a tuple made up of the sorted first parameter tuple and the new corresponding second tuple. For example, the following code fragment: tuple1 = (4, 1, 3) tuple2 (9, 8, 6) tuple3, tuple4 = get_sorted_in_parallel (tuplel, tuple2) print (tuplel, "-", tuple2) print (tuple3, "-", tuple4) prints: (4, 1, 3) - (9, 8, 6) (1, 3, 4) (8, 6, 9) 4 and 9 are connected, 1 and 8 are connected, 3 and 6 are…
