    Question Intersection between Two Sorted List

    Dear all,

    I need to seek help and am terribly stuck with.

    The question is :

    Given two sorted lists, L1 and L2, and write a procedure to compute L1 n L2 (intersection) using only the basic list operations.


    I need a full running program for this question.
    But i only managed to get some simple codings done, which i don't even know if i am right.

    My simple codes :

    stack nodes;
    while (L1_cur_node != NULL or L2_cur_node != NULL)
    if (L1_cur_node.data = = L2_cur_node.data) {
    nodes.push (L1_cur_node.data);
    L1_cur_node = L1_cur_node.next;
    L2_cur_node = L2_cur_node.next
    } else if (L1_cur_node.data < L2_cur_node.data) {
    L1_cur_node = L1_cur_node.next;
    } else {
    L2_cur_node = L2_cur_node.next;
    }
    }


    Can someone please help me with a full running program?

    Thank you.

    This is an ASSIGNMENT, I know this is an ASSIGNMENT. We will help if you have something but we won't write your damn assignment. Didn't you read the conditions when you signed up.

    Should be
    while (L1_cur_node != NULL and L2_cur_node != NULL)

    Algorithm seems OK, try turning it into actual C code - it's almost there as it is.


    > using only the basic list operations
    Start with these, and make sure they work, before trying the main problem.

    Thanks for reading.

    Thanks Salem!
    I have got it running and done this afternoon!
    Thanks for the correction. It was the intersection which i made a blunder.
