What is the value of the postfix expression 4 7 1 3 + – *?Options-1011274

The postfix expression is evaluated using a stack. Here are the steps:

1. Push 4 onto the stack.
2. Push 7 onto the stack.
3. Push 1 onto the stack.
4. Push 3 onto the stack.
5. Pop two elements from the stack, which are 3 and 1. Add them to get 4. Push 4 onto the stack.
6. Pop two elements from the stack, which are 4 and 7. Subtract 4 from 7 to get 3. Push 3 onto the stack.
7. Pop two elements from the stack, which are 3 and 4. Multiply them to get 12.

So, the value of the postfix expression 4 7 1 3 + - * is 12.
