Consider we have a stack that has the numbers 4, 1, 3 stored in that order. This means 4 is on top and 3 is at the bottom. How will our Stack look after the following lines of code are executed? Assume top is a reference to the node_t that represents the top of the stack.

Transcribed Image Text:Consider we have a stack that has the numbers 4, 1, 3 stored in that order. This means 4 is on top and 3 is at the bottom. How will our Stack look after the following
lines of code are executed? Assume top is a reference to the node_t that represents the top of the stack.
top = pop(top);
top = push(top, 3);
top = push(top, 1);
top = push(top, 4);
top = pop(top);
top = pop(top);
push(top, 7);
top
top = push(top, 2);
top = pop(top);
top = push(top, 1);
top = push(top, 2);
top = push(top, 2);
top = pop(top);
top = push(top, 1);
Type in how the Stack looks. Make sure to type in order from top to bottom your answer. Do not put spaces between the numbers.
