Here are some examples which will help you better understand the concept. Example 1: Input: a * ( b + c + d) Output: abc+d+* Example 2: Input: a*b Output: ab* Before discussing the solution of infix to postfix
If current character is ‘)’, then check if top of operator stack is opening bracket or not. If not pop two operands from operand stack, pop operator from operator stack and push stringoperator + operand1 + operand 2into operand stack. Keep popping from both stacks and pushing result into...
Write a program write a program called "infix.cpp", that uses a stack to convert a postfix expression to the corresponding fully-parenthesized infix expression. Consider the following examples: the postfix expressiona b + c d - *will be converted to the infix((a + b) * (c - d)) the...
pop operator from operator stack and push stringoperator + operand1 + operand 2into operand stack. Keep popping from both stacks and pushing result into operand stack until top of operator stack is an opening bracket.
