SAZZAD-AMT / Infix-to-Prefix-to-Postfix-Conversion-Assembly-code-by-c-program Star 2 Code Issues Pull requests While we use infix expressions in our day to day lives. Computers have trouble understanding this format because they need to keep in mind rules of operator precedence and also ...
我的问题是如何在这个函数中实现一个可用于所有递归调用的堆栈? (根据OP的评论更新;请参阅原始答案下方的新部分。) 使用堆栈列表并使其成为循环变量之一。例如。 (let loop ((stack (list)) ... ; other loop variables here, ; like e.g. what remains of the infix expression ) ... ; loop body )...
Infix : (A+B) * (C-D) ) Postfix: AB+CD-* 算法: 1. Scan the infix expression from left to right. 2. If the scanned character is an operand, append it to result. 3. Else 3.1 If the precedence of the scanned operator is greater than the precedence of the operator in the stack(...
中缀到后缀转换器 该程序采用中缀表达式,并使用链表实现的堆栈数据结构将其转换为后缀表达式。 向用户询问中缀表达式,程序将使用 convertToPostfix.java 类将其转换为后缀表达式,该类使用使用 LinkedStack.java 和 Node.java 类的链表实现的堆栈。点赞(0) 踩踩(0) 反馈 所需:1 积分 电信网络下载 ...
