+template <typename T>
+std::ostream& operator<<(std::ostream& os, const std::vector<T>& vec) {

+    for (size_t i = 0; i < vec.size(); ++i) {
+        os << vec[i]; // Print each vector element
+        if (i != vec.size() - 1) {
+            os << ", "; // Add separator between elements except after the last one
+        }
+    }
+    os << "]"; // Close vector formatting with a closing bracket
+    return os; // Return the stream to enable chaining
