6. Elements with At Least Two Significant Neighbors

Write a C++ program to find all elements in an array of integers that have at least two significant elements.

Sample Solution:

C++ Code :

#include<iostream> // Header file for input/output stream
using namespace std; // Using the standard namespace

// Function to find elements in the array which have at least two greater elements
void find_greater_elements(int nums[], int n)
{
    cout << "\nElements which have at-least two greater elements: "; // Output message to indicate displaying elements with at least two greater elements
    for (int i=0; i<n; i++)
    {
        int ctr = 0; // Counter to track the number of elements greater than the current element
        for (int j=0; j<n; j++)
            if (nums[j] > nums[i]) // Checking if the element at index 'j' is greater than the element at index 'i'
                ctr++; // Increment the counter if the condition is true

        if (ctr >= 2) // Checking if the counter value is greater than or equal to 2
            cout << nums[i] << " "; // Output the element which has at least two greater elements
    }
}

int main()
{
    int nums[] = {7, 12, 9, 15, 19, 32, 56, 70}; // Declaration and initialization of an integer array
    int n = sizeof(nums)/sizeof(nums[0]); // Calculating the number of elements in the array
    cout << "Original array: "; // Output message indicating the original array is being displayed
    for (int i=0; i < n; i++) 
    cout << nums[i] <<" "; // Output each element of the array

    find_greater_elements(nums, n); // Calling the function to find elements with at least two greater elements
    return 0;
}

Sample Output:

Original array: 7 12 9 15 19 32 56 70 
Elements which have at-least two greater elements: 7 12 9 15 19 32
