## Description

## Instructions
编写一个switch语句，测试val并设置以下条件的answer ：
1 - “alpha”
2 - “beta”
3 - “伽玛”
4 - “三角洲”
## Tests
```yml
tests:
- text: caseInSwitch(1)的值应为“alpha”
testString: 'assert(caseInSwitch(1) === "alpha", "caseInSwitch(1) should have a value of "alpha"");'
- text: caseInSwitch(2)的值应为“beta”
testString: 'assert(caseInSwitch(2) === "beta", "caseInSwitch(2) should have a value of "beta"");'
- text: caseInSwitch(3)的值应为“gamma”
testString: 'assert(caseInSwitch(3) === "gamma", "caseInSwitch(3) should have a value of "gamma"");'
- text: caseInSwitch(4)的值应为“delta”
testString: 'assert(caseInSwitch(4) === "delta", "caseInSwitch(4) should have a value of "delta"");'
- text: 您不应该使用任何if或else语句
testString: 'assert(!/else/g.test(code) || !/if/g.test(code), "You should not use any if or else statements");'
- text: 你应该至少有3个break语句
testString: 'assert(code.match(/break/g).length > 2, "You should have at least 3 break statements");'
```
