Write a function using iteration to print numbers from 1 to a given number, then extend it to print only even numbers, and finally modify it to accept a step size.

Data Structures & AlgorithmsMedium

Write a function that uses iteration to print all numbers from 1 to a given number. For example, if the input is 5, the function should print: 1, 2, 3, 4, 5. Now, extend this function to print only the even numbers within that range. For instance, if the input is 10, the output should be: 2, 4, 6, 8, 10. Finally, modify the function to accept a second argument, which represents the step size. Using iteration, print numbers starting from 1 up to the given number, incrementing by the step size. As an example, given the number 15 and a step size of 3, the expected output is: 1, 4, 7, 10, 13. Be sure to handle edge cases and invalid inputs appropriately.

Describe your approach to debugging malfunctions.

Behavioral

Let's discuss your approach to debugging malfunctions. Imagine you are on call for a critical e-commerce platform, and users start reporting that they are unable to complete their purchases. The error logs show a vague Transaction Failed message with no clear indication of the root cause. The customer service team is overwhelmed with complaints, and the business is losing revenue every minute the issue persists. Describe your initial steps in diagnosing the problem.** What tools or techniques would you use to gather more information? Would you focus on the front-end, back-end, or both? How would you prioritize your debugging efforts?** Would you start by examining the most recent code changes, monitoring server resources, or checking database connections? Explain your strategy for isolating the fault.** What methods would you employ to narrow down the potential causes of the malfunction, such as bisecting the code, using debugging tools, or performing hypothesis testing? Outline your approach to resolving the issue.** Once you have identified the root cause, what steps would you take to fix it quickly and effectively? How would you ensure that your fix does not introduce new problems? Discuss how you would prevent similar malfunctions from occurring in the future.** What proactive measures would you implement to improve the platform's reliability and resilience, such as adding better logging, implementing automated testing, or improving monitoring? Walk me through your thought process and provide specific examples of how you would tackle each step of the debugging process. I'm interested in hearing about your experience with similar situations and how you have successfully resolved them in the past.
