62. LED Toggle Class

Create a class LED that represents a simple LED connected to a microcontroller GPIO pin.

Your class must:

1. Store two private data members:
   • int pin → GPIO pin number (non-negative integer)
   • int state → LED state (0 = OFF, 1 = ON)
2. Provide a constructor that:
   • Accepts the GPIO pin number
   • Initializes the LED state to OFF
3. Provide the following public member functions:
   • void on() → sets the LED state to 1
   • void off() → sets the LED state to 0
   • void toggle() → flips the LED state (0 ↔ 1)
   • int status() → returns the current LED state (0 or 1)
4. In main():
   • Read three integers from input:
     • pin → GPIO pin number
     • initialState → initial LED state (0 or 1 only)
     • toggleCount → number of times to toggle the LED (≥ 0)
   • Create a LED object using the given pin
   • Set the initial LED state based on initialState
   • Call toggle() exactly toggleCount times
   • Print the final LED state (0 or 1) using status()

Example Input:

5
1
3

Example Output:

0

Explanation:
Start ON → toggle 3 times → OFF

Constraints:

• initialState is guaranteed to be either 0 or 1
• toggleCount is guaranteed to be a non-negative integer
• state and pin must be private
• Only class methods may modify state
• Output must be exactly one integer: 0 or 1
