Create a function withdraw that simulates a bank account withdrawal. It accepts the current balance and withdrawal amount as arguments. If the balance is sufficient, deduct the amount and return the new balance. Otherwise, return the original balance.

  • Implement a function withdraw with a return type of int and two int parameters (balance and amount).
  • Use an if statement to check if the balance is sufficient for the withdrawal.
  • If the balance is sufficient, return the new balance after subtracting amount.
  • If the balance is insufficient, return the original balance (balance variable).

Example

withdraw(500, 200) => 300
withdraw(500, 500) => 0
withdraw(200, 500) => 200
