How do you find the largest and second largest element in an array?
A simple way to find the largest and second-largest number is that sort the array in descending order and pick its first and second elements. Its first element will be the largest number and the second number will be the second-largest number. The time complexity of this solution is O(n log n).

How to find the largest element beaten by the largest?
To find the element beaten by the largest, and to avoid O (n) comparisons, we must store the index of the largest element in the previous row. That way we can easily check the adjacent elements. At any level (above root level),the adjacent elements are obtained as: where rootIndex is index of the largest (root) element at the previous level.
