Prefix Sum and left sum of binary tree involves calculating the sum of all nodes in a binary tree and the sum of nodes on the left side of each node.
Calculate prefix sum of binary tree by traversing in a pre-order manner and keeping track of the running sum.
To calculate left sum of binary tree, traverse the tree in a pre-order manner and keep track of the sum of nodes on the left side of each node.
Example: For a binary...

I applied via Job Portal and was interviewed in Feb 2024. There was 1 interview round.
I was interviewed before Dec 2020.
Round duration - 60 Minutes
Round difficulty - Medium
This round was purely based on Data Structures and Algorithms . One has to be fairly comfortable in solving Algorithmic problems to pass this round . Both the questions asked were quite common and luckily I had already prepared them from CodeStudio and LeetCode.
Given a Binary Tree with 'N' nodes, where each node holds an integer value, your task is to compute the In-Order, Pre-Order, and Post-Order traversals of the binar...
Compute the In-Order, Pre-Order, and Post-Order traversals of a Binary Tree given in level-order format.
Implement functions to perform In-Order, Pre-Order, and Post-Order traversals of a Binary Tree.
Use level-order input to construct the Binary Tree.
Traverse the Binary Tree recursively to generate the required traversals.
Ensure proper handling of null nodes represented by -1 in the input.
Return the three traversals as

Given two arrays A
and B
with sizes N
and M
respectively, both sorted in non-decreasing order, determine their intersection.
The intersection of two arrays in...
The problem involves finding the intersection of two sorted arrays efficiently.
Use two pointers to iterate through both arrays simultaneously.
Compare elements at the pointers and move the pointers accordingly.
Handle cases where elements are equal and update the intersection array.
Return the intersection array as the result.
