Error in solidity code

[YakshitAgarwal]

Original solidity code:

pragma solidity ^0.7.0;

contract MutexPattern {
bool locked = false;
mapping(address => uint256) public balances;

modifier noReentrancy() {
    require(!locked, "Blocked from reentrancy.");
    locked = true;
    _;
    locked = false;
}
// This function is protected by a mutex, so reentrant calls from within `msg.sender.call` cannot call `withdraw` again.
//  The `return` statement evaluates to `true` but still evaluates the `locked = false` statement in the modifier
function withdraw(uint _amount) public payable noReentrancy returns(bool) {
    require(balances[msg.sender] >= _amount, "No balance to withdraw.");

    balances[msg.sender] -= _amount;
    bool (success, ) = msg.sender.call{value: _amount}("");
    require(success);

    return true;
}

}

Error in the above code:
bool (success, ) = msg.sender.call{value: _amount}("");

Changed to:
(bool success, ) = msg.sender.call{value: _amount}("");
