49. Namespace Alias Usage

A vendor provides a very long namespace for its clock-control Hardware Abstraction Layer (HAL):

namespace VendorMegaChipCorporationUltraSeries9000_HardwareClockControlModule {
    void enableClock()  { cout << "CLOCK ENABLED"; }
    void disableClock() { cout << "CLOCK DISABLED"; }
}

Your tasks are:

1. Keep the long namespace exactly as provided.
2. Create a namespace alias named ClockHAL for the long vendor namespace.
3. Read an integer command cmd from standard input:
   • 1 → Enable the clock using the full namespace name
   • 2 → Disable the clock using the namespace alias

Example 1

Input:

1

Output:

CLOCK ENABLED

Example 2

Input:

2

Output:

CLOCK DISABLED

Constraints:

• You must use a C++ namespace alias.
• Do not modify the original vendor namespace name.
• Use standard input/output (cin, cout).
