Round duration - 60 minutes
Round difficulty - Medium
This was a technical round in the evening with a Software Engineer II which included a coding question along with a few questions on Core Java fundamentals.
I was given the option to either go for the coding round first or java theory. I realised that I might need more time for coding so I decided to opt for the coding round first, followed by the java related questions later.
The interviewer was extremely pleasant to speak with. He initially asked me to introduce myself and we spoke in depth about a project I worked on in my last organisation. The coding question was given on a google sheet but I was asked to code it on an online IDE without any special syntax correction features.

Minimum Count of Balls in a Bag Problem Statement
You are given an integer array
ARRof sizeN, whereARR[i]represents the number of balls in thei-thbag. Additionally, you have an integerM, which indi... - Ans. Brute force
Let 'X' be the maximum number of balls in a bag that we desire. Let ‘COUNT[i]’ be the number of operations that we need to perform on ‘ARR[i]’ such that the new bags made from it contain less than or equal to 'X' balls. Consider the following examples:
If we want 'X' to be ‘4’, then:
‘ARR[i] = 5’, after splitting we get [4, 1], so ‘COUNT[i] = 1’
‘ARR[i] = 8’, after splitting we get [4, 4] so ‘COUNT[i] = 1...

Interview Preparation Tips
Tip 1 : If you are a newbie to programming, I will strongly recommend to practice LC/GFG/CodingNinjas Easy questions for clearing the basics. Once you gain confidence, you can move on to tackle medium and hard questions.
Tip 2 : Most companies require individuals to know System Design well. For somebody with 1-3 years of experience, database designing (identifying entities, their relationships and constraints), OOP concepts and API designing for Low Level Design is a must. I would recommend the "System Design Interview by Alex Xu" book for HLD preparation.
Tip 1 : Have an updated and properly formatted resume
Tip 2 : The resume tells your story so you ought to know and be able to explain whatever you've written.
Tip 3 : Do not include technologies/skills that you've not worked on at all. It can blow the interview if the interviewer questions you about it.

- Ans. Backtracking
- Instead of checking all the places on the chessboard, we can use backtracking and place queen row-wise or column-wise.
- Suppose we place queens row-wise, and we start with the very first row. Place the queen and move to the next row until either there is a solution or there are no viable cells left.
