Coding problem1

The round was at 7.30 PM and I was asked to introduce myself and we had basic talk on where I live and my interests. I asked about the work culture and about the role at the end.

1. Puzzle

He showed a puzzle where n-balloons were there and I had to burst maximum balloons using an arrow.

Problem approach

This was basically finding a maximum number of points in a line. I coded that but he wanted an improved solution. He told me to assume the positions of balloons in a matrix where 1 represents if the balloon is present and vice versa. Then I had to find which row or column or diagonal had the maximum number of 1’s. Later he asked me if I had some questions.
