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。/ |. U% \* q4 r' n* f' f0 T
/ y; v) E8 i, `: B9 Z* x; F6 Z9 \/ G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。
7 m, ^/ F/ Z7 w7 C/ @) J6 H; y3 c% F
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。8 X& Y6 e$ P, z6 z& G& O
' n p' J& d$ R3 G5 }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;
