## Description
|
||
<section id="description"><p>实现一个以四位数字串为参数的函数，每个数字从1──►9（含），允许重复，并返回一个算术表达式，其值为24。如果不存在这样的解，则返回“没有解决方案。“ </p><p>规则： </p>只允许以下运算符/函数：乘法，除法，加法，减法除法应使用浮点或有理算术等来保留余数。不允许从提供的数字中形成多位数字。 （所以当给出1,2,2和1时，12 + 12的答案是错误的）。给定的数字顺序不必保留。 <p>示例输入： </p> <code>solve24("4878");</code> <code>solve24("1234");</code> <code>solve24("6789");</code> <code>solve24("1127");</code> <p>示例输出（字符串）： </p> <code>(7-8/8)*4</code> <code>3*1*4*2</code> <code>(6*8)/(9-7)</code> <code>(1+7)*(2+1)</code> </section>

- text: <code>solve24</code>是一个函数。
|
