Lower bound for sorting algorithms

WebA lower bound for an algorithm is the worst-case running time of the best possible algorithm for a given problem. The "on average" part here is important: there are many algorithms that run in very fast time if the inputted list is already sorted, or has some very particular (and overall unlikely) property.
