Process
-
OA (Pass all test cases)
-
There was a 3-round interview: the first 2 rounds were about coding, then technical things went through projects on the resume, followed by an HR call.
Questions
- What is a binary tree?
- What are the basic nodes of a tree?
- How do you find the left and right nodes of a tree?
- If you don't want to use a tree but still want to find a child based on the parent, consider an alternative. To achieve this without requiring more space than a tree, an array can be used. In this structure, the positions of parent and child are represented by indices, which can be calculated.
- Write code to find the left node and right node of a parent.
