Find the second biggest element from the array

Question

Ritik Sinha · Accepted Answer

EDIT:
A simple solution will be first sort the array in descending order and then return the second element from the sorted array. The time complexity of this solution is O(nlogn).

A more efficient solution:
1. Initialise two variable as "first" and "second" and set them to INT_MIN an arbitrary value ~ 10^10 and first = second = INT_MIN
2. Start traversing the array
3. if current element is > first then update first, that is first = current and second = first
      else if current second update second that is second = current
4. when finished traversing return second

I don't know why greater than and less than sign are not working 
Test 3 : greater than (>) and less than (<)
