Using the circular doubly linked list below, give the expression corresponding to each of the following descriptions. Node Node Node Node 4 Node For example, the expression for the i nfo value of node 1, referenced from refer- ence A, would be A getInfo() a. The i nfo value of nod ference C b. The i nfo value of node 2, referenced from referenceB c. The 1 i nk value of node 2, referenced from reference A d. The 1 i nk value of node 4, referenced from referenceC e. Node 1, referenced from reference B f. The back value of node 4, referenced from referenceC g. The back value of node 1, referenced from reference A e I, referenced from re
