EusLisp is a dialect of the Lisp programming language designed for writing robot programs. It was created by Luis von Ahn and Dana Angluin at the University of Maryland, College Park in 1994. EusLisp is based on Scheme, a subset of Lisp, and adds features specifically for robot programming, such as support for sensor data and actuator control. EusLisp is open-source software and is available for download from the EusLisp website.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with EusLisp Robot Programming Language.

What does this simple EusLisp code snippet do?
(print "Hello, World!")
This code prints the string 'Hello, World!' to the standard output.
Can you explain what this EusLisp code is doing?
(setq x 5)
(setq y 10)
(+ x y)
This code first sets the value of 'x' to 5 and 'y' to 10. Then, it adds 'x' and 'y' together. The output will be 15.
What is the purpose of this EusLisp code snippet?
(setq arr (make-list 5 :initial-element 0))
(dolist (i arr) (print i))
This code creates a list with 5 elements, all initialized to 0. Then, it iterates through the list and prints each element.
What will be the output of the following EusLisp code?
(defun worker (x)
 (sleep x)
 (print x))

(dotimes (i 5)
 (threads:make-thread #'worker :arguments (list i)))
This code creates a function 'worker' that takes an argument, sleeps for that many seconds, then prints the argument. It then creates 5 threads that each run the 'worker' function with a different argument. The output will be the numbers 0 to 4 printed in an unpredictable order due to the nature of threading.

Wrap-up questions

Final candidate for EusLisp Robot Programming Language Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle EusLisp Robot Programming Language application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between 'let' and 'let*' in EusLisp.

'let' and 'let*' both are used to bind variables. The difference is that 'let' binds variables simultaneously, while 'let*' binds variables sequentially.

What is the purpose of the 'apply' function in EusLisp?

'apply' is used to call a function with arguments that are contained in a list.

How would you implement recursion in EusLisp?

Recursion in EusLisp can be implemented by defining a function that calls itself as part of its execution.
