广义上infix是给user看的,prefix和postfix很大程度上是给编译器看的。具体地,对于单操作符运算,其实用的是prefix(比如取非),当然常见的prefix/postfix就是++、--,但是python中没有这个操作符。 有用 回复 查看全部 1 个回答 推荐问题 字节的 trae AI IDE 不支持类似 vscode 的 ssh remote 远程开发怎么办? 尝...

It's actually quite common to have a function call pass one parameter, where the parameter is calculated using infix notation. Thus, there's a rule to simplify this common case (the prefix {} rule). So factorial{n - 1} maps to factorial({n - 1}) which maps to (factorial (- n 1...

Given an infix expression, convert it to the postfix expression. Assume that the infix expression is a string of tokens without any whitespace. For example, Input:A*B+C Output:AB*C+ Input:(A+B)*(C/D) Output:AB+CD/* Input:A*(B*C+D*E)+F ...
