\[(8+3)\times (5-4)\]

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?
