Q. Which data structure would you use to implement a first-in, last-out behavior?
Stack
Stack is a data structure that follows the Last In First Out (LIFO) principle.
Elements are added and removed from the same end, known as the top of the stack.
Common operations include push (add element), pop (remove element), and peek (access top element).

Q. What is the difference between call by value and call by reference?
Call by value passes a copy of the value, while call by reference passes the memory address of the value.
Call by value creates a new copy of the value being passed.
Call by reference allows the called function to modify the original value.
In call by value, changes made to the parameter inside the function do not affect the original value.
In call by reference, changes made to the parameter inside the function affect the original value.
Call by value is used when the original val...read more

Q. What are the differences between PLA and Nylon in the context of 3D printing?
PLA and Nylon are two different materials used in 3D printing with distinct properties.
PLA (Polylactic Acid) is a biodegradable thermoplastic derived from renewable resources like cornstarch or sugarcane.
Nylon (Polyamide) is a synthetic thermoplastic known for its strength, durability, and flexibility.
PLA is easier to print with due to its low melting point and minimal warping, making it suitable for beginners.
Nylon has a higher melting point and requires a heated print bed, ...read more
