Question 8409 – Data-Structures

→ ’10’ is pushed in the stack

→ ‘5’ is pushed in the stack

→ ‘+’ comes so addition will be done by popping the top two elements in the stackand the result is pushed back into the stack, i.e., 10+5 = 15

→ 60 pushed in the stack

→ 6 pushed in the stack

→ ‘/’ comes. So, 60/6 = 10

→ ‘*’ comes. So, 15 * 10 = 150

→ ‘8’ comes, push in the stack


→ ‘-‘ comes. So, 150-8 = 142

So the final result is 142.
