[Omi-code404]

🚀 What's Added?

• Recursive binary search algorithm implementation
• Standard C programming conventions followed
• Basic error handling added

🧪 Testing Details

c
int main() {
int arr[] = {2, 5, 8, 12, 16, 25, 38, 56, 72, 91};
int index = binary_search(arr, 0, 9, target);
assert(index == 2); // Test case
}

✅ Checklist

• Code reviewed
• All test cases passed
