Respuesta :
An infix expression is a type of expression in which an expression is written in a conventional or standard format. The operators are placed between the operands in this notation. Infix expression examples include A+B, A*B, A/B, and so on.
A prefix expression is another form of expression, but it does not require other information such as precedence and associativity, whereas an infix notation does. It is also referred to as polish notation. An operator comes before the operands in prefix notation.
The following are the rules for converting an infix expression to a prefix expression:
- To begin, reverse the infix expression provided in the problem.
- From left to right, scan the expression.
- Print the operands as they arrive.
- If the operator arrives and the stack is empty, simply insert the operator into the stack.
- Push the incoming operator into the stack if it has a higher precedence than the TOP of the stack.
- Push the incoming operator into the stack if it has the same precedence as a TOP of the stack.
- If the incoming operator has a lower precedence than the TOP of the stack, pop and print it. Test the incoming operator again against the top of the stack and pop the operator from the stack until it finds an operator with a lower or equal precedence.
- If the incoming operator has the same precedence as the top of the stack and is, then pop the top of the stack until the condition is met. If the condition is false, press the operator.
- Pop and print all the operators from the top of the stack when we reach the end of the expression.
- Push it into the stack if the operator is ')'.
- If the operator is '(,' then it will pop all the operators from the stack until it finds an opening bracket in the stack.
- Push the operator onto the stack if the top of the stack is ')'.
- Finally, reverse the output.
