The answer is the number of inversions in the array, which is the number of pairs i,j such that i < j and a[i] > a[j]. Counting this is a fairly classical problem with many solutions such as using data structures such as Balanced Trees or Binary Indexed Trees. Another particularly elegant solution involves modifying merge sort to count the number of inversions when merging the two sorted halves in the algorithm.

Defination of the System Load Value: Basically, load average is the amount of traffic to your CPU(s) over the past 1, 5, and 15 minutes. Generally you want this number to be below the number of CPU(s)/cores you have. 1.0 on a single core machine means it's using the CPU to it's maximum, and anything above that means things are getting queued.

The fglrx shipped with Precise has some compatility issues
with the kernel 3.2.0-29, which can cause a freeze when 
shutting down, everything stops on the plymouth screen.

Replace either of them can solve this problem.
