Question: How is sorting defined as (n+m) log(n+m)? Shouldn't it be nlogn +mlogm?

[tseth92]

nlogn for drives and mlogm for keyboard. So, if you sort both independently, shouldn't it be mlogm+nlogn , instead of (m+n)log(m+n) ?

This is Big O notation signifying the class of problem. This post should help explain how the notation works and the mathematical thought behind it: http://forums.codeguru.com/showthread.php?491516-how-is-O(logm-logn)-O(log(m-n))-O-is-big-oh
