I can perform a merge sort to order a list.

Show transcript
Merge sort splits items in lists into individual lists before merging pairs of lists together till all items are sorted. Merge sort is an efficient “divide and conquer” algorithm that can perform well in real world use. A merge sort algorithm is usually faster to execute but more complex to write than bubble sort. Executing a merge sort takes up extra space in memory.
