当扫描到A时,将A添加到postfix中,接着遇到‘+’操作符,此时,由于只有一个操作数,‘+’只能先存入栈stack中;当扫描到B时,将其追加至postfix;接着遇到*,栈不为空,那么调用pcdr(pop(stack),’*’),因为‘+’优先级低于‘*’,返回False,将‘*’压入栈中,push(stack,’*’),接着遇到C,将其追加至...
Convert Infix to Prefix Notation To convert an infix to Prefix, first we’ve to know how to convert Infix to postfix notation. Initially we’ve astringS which represent the expression in infix format. Reverse thestringS. After reversing A+B*C will become C*B+A. Note while reversing each ...

I have written a C++ program to convert an infix expression to postfix expression using recursion. I would like to know if it can be improved if possible. Can we improve it by not usingastack? I am using avectorvector<char>as a stack here. The following is my code: #include<iostream>...
postfix.push_back(st.top()); st.pop(); } st.push(infix[i]); } } while(!st.empty()){ postfix.push_back(st.top()); st.pop(); } return postfix; } int main() { // your code goes here string infix="a*(b+c+d)"; string postfix=infixToPostfix(infix); cout<<"Infix expres...
returnpostfix.TakeWhile(item => item != null).ToArray(); } 看答案 如果你替换array由A.Stack<string>,你不必跟踪你在哪里index多变的。 然后,您可以返回结果postfixStack.ToArray() 我的实施方式: publicstaticstring[] InfixToPostfix(string[] infixArray ) ...
