56533eb9ac21ba0edf2244df	Multiple Identical Options in Switch Statements	1		交换机语句中的多个相同选项

Description

如果从switch语句的case省略了break语句，则会执行以下case语句，直到遇到break 。如果您有多个具有相同输出的输入，则可以在switch语句中表示它们，如下所示：

switch（val）{
情况1：
案例2：
案例3：
result =“1,2或3”;
打破;
案例4：
result =“4 alone”;
}

1,2和3的情况都会产生相同的结果。

Instructions

写一个switch语句来设置以下范围的answer ：
1-3 - “低”
4-6 - “中”
7-9 - “高” 注
您需要为范围中的每个数字都有一个case语句。

Tests

tests:
  - text: <code>sequentialSizes(1)</code>应返回“Low”
    testString: 'assert(sequentialSizes(1) === "Low", "<code>sequentialSizes(1)</code> should return "Low"");'
  - text: <code>sequentialSizes(2)</code>应该返回“Low”
    testString: 'assert(sequentialSizes(2) === "Low", "<code>sequentialSizes(2)</code> should return "Low"");'
  - text: <code>sequentialSizes(3)</code>应返回“Low”
    testString: 'assert(sequentialSizes(3) === "Low", "<code>sequentialSizes(3)</code> should return "Low"");'
  - text: <code>sequentialSizes(4)</code>应返回“Mid”
    testString: 'assert(sequentialSizes(4) === "Mid", "<code>sequentialSizes(4)</code> should return "Mid"");'
  - text: <code>sequentialSizes(5)</code>应返回“Mid”
    testString: 'assert(sequentialSizes(5) === "Mid", "<code>sequentialSizes(5)</code> should return "Mid"");'
  - text: <code>sequentialSizes(6)</code>应返回“Mid”
    testString: 'assert(sequentialSizes(6) === "Mid", "<code>sequentialSizes(6)</code> should return "Mid"");'
  - text: <code>sequentialSizes(7)</code>应该返回“High”
    testString: 'assert(sequentialSizes(7) === "High", "<code>sequentialSizes(7)</code> should return "High"");'
  - text: <code>sequentialSizes(8)</code>应该返回“High”
    testString: 'assert(sequentialSizes(8) === "High", "<code>sequentialSizes(8)</code> should return "High"");'
  - text: <code>sequentialSizes(9)</code>应该返回“High”
    testString: 'assert(sequentialSizes(9) === "High", "<code>sequentialSizes(9)</code> should return "High"");'
  - text: 您不应该使用任何<code>if</code>或<code>else</code>语句
    testString: 'assert(!/else/g.test(code) || !/if/g.test(code), "You should not use any <code>if</code> or <code>else</code> statements");'
  - text: 你应该有九个<code>case</code>陈述
    testString: 'assert(code.match(/case/g).length === 9, "You should have nine <code>case</code> statements");'
