Maintain the stack’s bottom entry in stack[stack. The key benefit of an array data structure is that it offers fast O(1) search if you know the index, but adding and removing an element from an array is slow because you cannot change the size of the array once it’s created. We can use C++ STL to solve this problem by calculating the difference between each adjacent element, and returning the minimum value of the array.
