Goldman Sachs Interview Experience | Set 19 (For Technical Analyst Post)

The pre-interview selection round had common Aptitude Questions and a Coding question.

For Apti we had 20 questions – Solving Time (30 minutes) ( Questions were moderate not so easy again not so difficult )
For Coding – 1 question – Solving Time (1 hour ) ( Coding question was very easy )

Here’s the question as far as I remember:

A binary tree has to be filled with characters ‘S’ and ‘D’. ‘S’ means alive nodes and ‘D’ means dead nodes. ‘S’ node bears 2 children or 1 child and ‘D’ node bears no child at all. For indicating no nodes we use the character ‘X’.

The tree input was given in level order.

Output: Find the level which contains maximum number of ‘S’

Solution hints:

Find a) number of nodes from the tree b) level of the tree from the given nodes c) construct a for loop such that it iterates through each level and keep a count of the number of S encountered d)Print the level which has the maximum ‘S’
