\[(8+3)\times (5-4)\]
To evaluate the above expression, we use first convert it to reverse polish format using a shunting yard algorithm. Which of the following represent the correct order of reverse polish notation, when the above expression is evaluated?
\(A) 8, 3, +, 5, 4, -, \times\)
\(B) 8, +, 3, \times, 5, -, 4\)
\(C) 8, +, 3, 5, 4, -,\times\)
\(D) 8, +, 3, 5, -, 4, \times\)
\[1\times 2 + 2 \times 5 / 7\]
To evaluate the above expression, we use first convert it to reverse polish format using a shunting yard algorithm. Which of the following represent the correct order of reverse polish notation, when the above expression is evaluated?
\(A) 1, 2, 2, 5, \times, /, 7, \times +\)
\(B) 1, 2, 2, 5, \times, \times, 7, / +\)
\(C)1, 2, \times, 2, 5, \times, 7, /, + \)
\(D) 1, 2, \times, 2, 5, /, 7, \times, +\)
A polish expression or postfix expression is a notational form for logic, arithmetic, and algebra which places operators to the left of their operands. What is the value of the polish expression below when evaluated?
\[\large{35\ 17\ 40\ 9\ - * + 7 - }\]
