Every time it has to identify two arrays to combine, perform the following to create a bottom-up mergesort that benefits from array order: Locate the first entry in a sorted subarray, then the second, and finally merge them (by increasing a pointer until it finds an element in the array that is smaller than its predecessor). Consider the array size and the number of maximal ascending sequences in the array when calculating the algorithm's execution time.
