# --description--
If the `break` statement is omitted from a `switch` statement's `case`, the following `case` statement(s) are executed until a `break` is encountered. If you have multiple inputs with the same output, you can represent them in a `switch` statement like this:
```js
var result = "";
switch(val) {
case 1:
case 2:
case 3:
result = "1, 2, or 3";
break;
case 4:
result = "4 alone";
}
```
Cases for 1, 2, and 3 will all produce the same result.
# --instructions--
Write a switch statement to set `answer` for the following ranges:
`1-3` - "Low"
`4-6` - "Mid"
`7-9` - "High"
**Note**
You will need to have a `case` statement for each number in the range.
# --hints--
`sequentialSizes(1)` should return "Low"
```js
assert(sequentialSizes(1) === 'Low');
```
`sequentialSizes(2)` should return "Low"
```js
assert(sequentialSizes(2) === 'Low');
```
`sequentialSizes(3)` should return "Low"
```js
assert(sequentialSizes(3) === 'Low');
```
`sequentialSizes(4)` should return "Mid"
```js
assert(sequentialSizes(4) === 'Mid');
```
`sequentialSizes(5)` should return "Mid"
```js
assert(sequentialSizes(5) === 'Mid');
```
`sequentialSizes(6)` should return "Mid"
```js
assert(sequentialSizes(6) === 'Mid');
```
`sequentialSizes(7)` should return "High"
```js
assert(sequentialSizes(7) === 'High');
```
`sequentialSizes(8)` should return "High"
```js
assert(sequentialSizes(8) === 'High');
```
`sequentialSizes(9)` should return "High"
```js
assert(sequentialSizes(9) === 'High');
```
You should not use any `if` or `else` statements
```js
assert(!/else/g.test(code) || !/if/g.test(code));
```
You should have nine `case` statements
```js
assert(code.match(/case/g).length === 9);
```
# --seed--
## --seed-contents--
```js
function sequentialSizes(val) {
var answer = "";
// Only change code below this line
// Only change code above this line
return answer;
}
sequentialSizes(1);
```
# --solutions--
```js
function sequentialSizes(val) {
var answer = "";
switch(val) {
case 1:
case 2:
case 3:
answer = "Low";
break;
case 4:
case 5:
case 6:
answer = "Mid";
break;
case 7:
case 8:
case 9:
answer = "High";
}
return answer;
}
```
