Linked list Sorting  No moving of data like in the array.  But just exchange the links when needed. 1 link NULL 1 link NULL After Sorting Before Sorting SourceLens.org Copyright. All rights reserved. Content Owner - Meera R (meera at sourcelens.org)

Complications? How to deal?  Try to get a reasonable understanding of the algorithm or the “logic”.  Give your best effort to implement the logic by yourself even though you are sure you may not be able to do it.  Debug, Debug and Debug. Make sure your stepping and breakpoint goes into all the if else cases in multiple iterations.  Now look at working implementation.  Debug and modify the working implementation.  If you don’t understand a line comment out that line and see what difference it makes in the working implementation.  See if you can make your implementation work?  Don’t Try to understand the working implementation without having a proper understanding of the logic. Try to understand the working implementation without a sincere attempt from your side. Try to look at code of the working implementation and try to understand the follow without debugging. Remember you are not a computer you have to “think” and act like a CPU to understand the flow without the help of a debugger. SourceLens.org Copyright. All rights reserved.

If you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. Linus Torvalds. Linux kernel coding style document -  Unfortunately all the code your manager will ask you to understand and/or enhance/fix is not written by Linus or Linux Kernel.  You need to get familiarize with all kind of complications and complexities when it comes to code written by others.
