18. GPIO Pin Toggle

Create an inline function that toggles the state of a GPIO pin.

Each pin state is represented as:

• 0 → LOW
• 1 → HIGH

Your inline function must:

• Take the current pin state as input
• Return the toggled state:
  • 0 → 1
  • 1 → 0

In main():

• Read the initial states of exactly 10 GPIO pins (space-separated, index 0–9).
• Read an integer n, the number of toggle operations.
• Read n pin indices.
• For each pin index:
  • Toggle the corresponding pin every time it appears.
• Print the final states of all 10 pins, separated by spaces.

Example 

Input:

0 1 0 1 0 1 0 1 0 1
3
0 1 0

Output:

0 0 0 1 0 1 0 1 0 1

Explanation of Example:

• Toggle pin 0 → 0 → 1
• Toggle pin 1 → 1 → 0
• Toggle pin 0 again → 1 → 0

Final state:

0 0 0 1 0 1 0 1 0 1

Input Constraints:

• Pin states are guaranteed to be either 0 or 1
• Pin indices are guaranteed to be in the range 0 to 9
• 0 ≤ n ≤ 10^5
• No global variables may be used
• Toggling must be performed using an inline function
