Rewrite the following if statement as an equivalent switch statement. The variable digit is of type int.

```
if (digit == 0)
value = 3;
else if (digit == 1)
value = 3;
else if (digit == 2)
value = 6;
else if (digit == 3)
value = 9;
```

```
switch (digit) {
case 0:
case 1:
value = 3;
break;

case 2:
value = 6;
break;

case 3:
value = 9;
}
```
