I wanted to make an infix to prefix converter. When I ran the code, the operator in the string sends all the operators in the beginning of the returning string. How can I fix the code below? classStack:def__init__(self): self.a = []defisEmpty(self):returnself.a == []defpush(...

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 brackets. Prefix and Postfix expressions are easier for a computer to understand and evaluate...
