Fоr questiоns 31 tо 35 pleаse refer to the following question, exаmple, sаmple solution. Reverse polish notation (RPN) places the operands first, followed by the operator. For example, the RPN of "(3 + 4) * 5 - 6" is "3 4 + 5 * 6 -". The function below implements an evaluator for RPN expressions. #include #include #include #include #include int evaluateRPN(const std::string& expr) { std::stack st; std::istringstream iss(expr); std::string token; while (iss >> token) { if (token == "+" || token == "-" || token == "*" || token == "/") { int right = st.top(); st.pop(); int left = st.top(); st.pop(); int result = 0; if (token == "+") result = left + right; else if (token == "-") result = left - right; else if (token == "*") result = left * right; else { result = left / right; } st.push(result); } else { st.push(std::stoi(token)); } } return st.top();} What is the primary role of the stack data structure in the evaluation of an RPN expression?
