SDE - Intern

You are given an integer array 'ARR' of size 'N' and an integer 'S'. Your task is to return the list of all pairs of elements such that each sum of elements of each pair equals 'S'.

Note:

Each pair should be sorted i.e the first value should be less than or equals to the second value. 

Return the list of pairs sorted in non-decreasing order of their first value. In case if two pairs have the same first value, the pair with a smaller second value should come first.

1. My interview started with an introduction and then my college life and what I like to do in college.
2. Then, they asked me about my internship, which I was doing then. We discussed the projects and technologies I learned and was doing during my internships.
3. Then they came straight to my college life, like how many friends I had and my relationship with them.
4. They also asked me situational questions like, "What if I had a fight with someone and now that person is hating and speaking nonsense of you, so what will I do?"
5. Then, they asked me about my most significant achievement when my parents were proud of me. I didn't have any recent such significant achievements, so I told them about one from my senior school. They were more than happy to listen to that and even congratulated me.
6. Then, they asked me behavior questions and about some teamwork and leadership situations.
7. We discussed about my hobbies and how often I do them.
8. We discussed my school projects and some volunteering work I did.
9. Overall, it was a pleasant experience. They were very encouraging, and that helped me boost my confidence.
