```csharp
public static bool FlipBit(ref string writeVector, string Replica)
```

toggle one of the bits in writeVector and return the new value.

### Parameters

- `writeVector` (`string`): The write vector in which we want to flip the bit
- `Replica` (`string`): The replica for which we want to flip the bit

### Returns

the state of the bit after flipping it
