What does the following code snippet do?
#include <iostream>
using namespace std;
int binarySearch(int arr[], int n, int key) {
    int low = 0, high = n - 1;
    while (low <= high) {
        int mid = low + (high - low) / 2;
        if (arr[mid] == key)
            return mid;
        if (arr[mid] < key)
            low = mid + 1;
        else
            high = mid - 1;
    }
    return -1;
}
int main() {
    int arr[] = {2, 4, 6, 8, 10};
    int key = 6;
    int result = binarySearch(arr, 5, key);
    cout << result;
    return 0;
}
  • a)
    Implements binary search iteratively on a sorted array and returns the index of the key element if found, -1 otherwise.
  • b)
    Implements linear search iteratively on an unsorted array and returns the index of the key element if found, -1 otherwise.
  • c)
    Implements binary search recursively on a sorted array and returns the index of the key element if found, -1 otherwise.
  • d)
    Implements linear search recursively on an unsorted array and returns the index of the key element if found, -1 otherwise.
Correct answer is option 'A'. Can you explain this answer?
