39. Resolve Driver Collision

Two different motor driver modules define a function named init().
Without namespaces, these functions conflict.

Your task is to organize them into two namespaces and call the correct one based on input.

Create two namespaces:

DriverA containing:

• void init() → prints "A INIT"

DriverB containing:

• void init() → prints "B INIT"

In main():

• Read an integer x
  • If x == 1 → call DriverA::init()
  • If x == 2 → call DriverB::init()

Example 1

Input:

1

Output:

A INIT

Example 2

Input:

2

Output:

B INIT

Constraints:

• Use namespaces to separate both drivers
• Do not rename functions; both must be named init()
