Coding problem2
The selection process is fairly simple and consists of just one coding round, having 2 problems, based on basic concepts of Data Structures And Algorithms. The time limit was 1 hour. There were various sets having different questions, but the difficulty level was uniform for all sets.
The 2 questions in my set were:
Given two binary strings, find and return the sum of those two numbers represented by those strings.
Check If Two Nodes Are Cousins

Asked in companies
You have been given two binary strings ‘A’ and ‘B’. Your task is to find the sum of both strings in the form of a binary string.
Binary strings are the representation of integers in the binary form. For example, the binary strings of 9 and 16 are “1001” and “10000” respectively.
Problem approach
The idea is to start from the last characters of two strings and compute the digit sum one by one. If the sum becomes more than 1, then store carry for the next digits.
2. Check If Two Nodes Are Cousins

Asked in companies
You are given an arbitrary binary tree consisting of N nodes, where each node is associated with a certain value, and two node values, a and b, you need to check if these nodes are cousins.
Two nodes are cousins of each other if they are at the same level and have different parents. Two nodes are said to be at the same level if the distance of both the nodes from the root node is the same.
A binary tree (BT) is a data structure in which each node has at most two children.
For the given binary tree:
4 and 7 are cousins of each other since they are at the same level and have different parents, 3 and 2 respectively.
