Merge sort belongs to the group of "divide and conquer" algorithms. It is very efficient (runs in O (n * log 2 n)) and makes low number of comparisons. One disadvantage is the amount of extra space that it requires. Normally this sorting is stable, meaning that it preserves the order of equal elements.
