给出四个数字,要求,在其间添加运算符和括号,使得计算结果等于24。) l j+ @; @4 L& K" i' v( K
, W* k3 }# Y7 y. B括号的放置即为决定哪几个数先进行计算。所以,我们先确定首先进行计算的两个相邻的数,计算完成后,就相当于剩下三个数字,仍需要在它们之间添加符号;然后再决定在这三个数中哪两个相邻的数先计算。由此,我们就成功解决了数字的运算次序问题,此时不需要再考虑不同运算符号的优先级问题,因为括号的优先级高于加减乘除。
; @% F$ u) c. P7 K& r7 ]7 B6 k4 U) R9 i0 |0 I; D- B; A
通过循环,我们可以得到第一第二第三次计算的运算符,再通过计算,就可以得出和,若和等于24,即为所求解。

在输出格式中,由于括号的放置共六种情况,故根据计算先后顺序的不同,输出时在不同地方放置括号;
