    Question Is Sedgewick's a good book to follow?

    I am sorry, if this is a wrong question in this forum.

    It has been quite a while since I have coded in C and last week, I decided to finish atleast one Algo book cover to cover(or atleast try), thus revising C. I picked up Sedgewick on the advice of a few friends and also ACCU review.

    But is the book really good? Does the code in it work?

    I tried running a few and already there are so many errors. I started with the 4th chapter and the code on Josephes election, reversing the list etc are already not working. Infact in solving Josephes election problem using a circular list, I rubbed my eyes when I saw

    N--

    right at the end of the code, which was there for I dont know why.

    Never mind the silly naming style of the variables. Any opinions?

    Thanks and I am sorry again if it was not the right forum.

    Anoop.

    Yes, it is.

    >Does the code in it work?
    No. Sedgewick is a believer in reusing previous work, so most of the code is a poor Pascal to C conversion. If you want solid algorithms to write code from then I suggest Knuth's texts. Sedgewick gives excellent explanations, but his C code is just awful most of the time.

    >which was there for I dont know why
    I think you read the code wrong. My copy shows "N--;" inside of the last loop:
    Code:
    while (x != x->next)
      {
        for (i = 1; i < M; i++) x = x->next;
        x->next = x->next->next; N--;
      }
    printf("%d\n", x->item);
    My best code is written with the delete key.

    Precisely. I am also refering to the same statement. I am unable to comprehend the need for N--;

    Oh, I see. There is none, you can safely remove it. If N were used later for the number of items then decrementing it would make sense. But as it stands, there's no point.
