Expression Evaluation

December 23, 2023

Problem # Given a mathematical expression represented as a string (e.g., “(2 + 3) * 4 / 2”), design an algorithm to evaluate the expression and return the result. Solution # import operator def evaluate_expression(expression): def apply_operator(ops, values): # Apply the operator to the top two values in the values stack operator = ops.pop() right = values.pop() left = values.pop() values.append(operations[operator](left, right)) operations = {'+': operator.add, '-': operator.sub, '*': operator. ...
