I'm preparing for the job interview. One of the topics I'm studing is algorithms analysis, which uses so called [Big O notation](http://en.wikipedia.org/wiki/Big_O_notation). So, the problem is, I actually don't know how to properly pronounce those designations, for example, `O(n log n)`. A few more examples [here](http://en.wikipedia.org/wiki/Big_O_notation#Orders_of_common_functions). 

The most interesting case is `O(n log n)`, because here we have a function `O`, multiplication `n * log n` and logarithm `log n` together.

Thanks.
