What is a race condition?
... more threads can access shared data and they try to change it at the same time. Because the thread scheduling algorithm can swap between threads at any time, you don't know the order in which the threads will attempt to access the shared data. Therefore, the result of the change in data is dependen...
Difference between static and shared libraries?

...sonable to expect that you cannot do any better than O(N log N) in running time.
However, the interesting part is to investigate whether you can sort it in-place, stably, its worst-case behavior and so on.
Simon Tatham, of Putty fame, explains how to sort a linked list with merge sort. He concl...
