通过使用集合中的每个数字{1,2,3,4},恰好一次,并利用四个算术运算(+, - ,\*,/)和括号/括号,可以形成不同的正整数目标。例如,8 =(4 \*(1 + 3))/ 2 14 = 4 \*(3 + 1/2)19 = 4 \*(2 + 3) - 1 36 = 3 \* 4 \*(2 + 1)注数字的连接,如12 + 34,是不允许的。使用集合{1,2,3,4},可以获得31个不同的目标数,其中36个是最大的,并且在遇到第一个不可表达之前可以获得数字1到28中的每一个。数。找到四个不同数字的集合,a <b <c <d,可以获得最长的一组连续正整数,1到n,给出你的答案字符串:abcd。

# --hints--
|
||
|
||
`euler93()`应返回1258。
|
||
|
||
```js
|
||
assert.strictEqual(euler93(), 1258);
|
||
```

function arithmeticExpressions() {
|
||
|
||
return true;

}
|

|
||
arithmeticExpressions();
