Question 1
1. (MySQL) You are given a table, BST, containing two columns: N and P, where N represents the value of a node in Binary Tree, and P is the parent of N. Write a query to find the node type of Binary Tree ordered by the value of the node. Output one of the following for each node:
Root: If node is root node.
Leaf: If node is leaf node.
Inner: If node is neither root nor leaf node.
2. (Python)The Missing Number problem requires finding the only number missing from an array nums containing ( n ) distinct numbers in the range ([0, n]). The problem has an efficient solution with ( O(n) ) runtime and ( O(1) ) extra space.
The interview process was smooth and well organized. It started with an initial recruiter screening, followed by a technical assessment focused on coding, problem-solving, Java backend concepts, data structures, and system design basics. The interviewer was professional, explained the expectations clearly, and gave time to discuss my approach before coding.
