Recall that an algorithm is a systematic procedure to perform an operation on data. Here, the operation determines if the list is in order. The algorithm is:
For each pair of integers starting at the left: if any pair is out of order, the list is not in order
If one pair is out of order the entire list is out of order.
Is the pair 23 23 out of order?
