While doing linear scan, it would take 2*(n-1) comparisons in the worst case to find both minimum as well maximum in one pass. Solve smaller instance 3. In-order traversal of a Binary Search Tree lists the nodes in ascending order. Similarly, decrease and conquer only requires reducing the problem to a single smaller problem, such as the classic Tower of Hanoi puzzle, which reduces moving a tower of height n to moving a tower of height n − 1.
