SDE - Intern

You are given a positive integer 'N'. Your task is to return all the prime numbers less than or equal to the 'N'.

Note:

1) A prime number is a number that has only two factors: 1 and the number itself.

2) 1 is not a prime number.

       bool a = true;
       bool b = false;
       int x = 10;
       int y = 5;
       p = ((x | y) + (a + b));
       cout << p;
       return 0;

During the interview, I was asked about Redis, which I had mentioned in my resume. The interviewer wanted to know how I would implement Redis in a real project. I explained that Redis can be used for caching frequently accessed data—like product details on an e-commerce website—to reduce database load and improve response time. I also mentioned that Redis can store user sessions or authentication tokens for faster access in a web application. They wanted to assess whether I truly understood the purpose and practical usage of Redis, beyond just listing it on my resume.
