Round duration - 70 minutes
Round difficulty - Medium

It was held at 7:00 pm. STL functions were not allowed. But STL containers like queues were allowed. One question was easy-medium, one was medium and one was hard. Everyone got different sets of questions. Make sure you solve all the questions from Samsung online Test, as they tend to repeat. Only 2 sample test cases were visible and Other Test Cases were hidden.

Q1. Game of Stones
Given the count of total stones in a game. Two-player ‘Ale’ and ‘Bob’ are playing the game. Your task is to find who will win the game if both the players are playing optimally.
Rules of t...read more
Ans. Game Theory
• It is clear that if the number of stones is ‘1’ then ‘Ale’ wins the game. If ‘2’ then also ‘Ale’ wins the match, and if ‘3’ then ‘Bob’ wins the game.
• So we can observe that, if anyone has a chance to choose a stone from ‘3’ number of stones then another opponent will the game. If ‘Ale’ choosing the stones from ‘3’ number stone then ‘Bob’ will win and vice versa.
• If the number of stones is ‘4’ then ‘Ale’ will w...read more

Q2. Largest Number in Binary Tree
You have been given a Binary Tree of 'N' nodes where the nodes have integer values.
Your task is to find the largest number that could be formed by concatenating all...read more
Ans. Sorting
A simple solution would be to store all the node values to the list/array by traversing the whole Binary Tree and the problem now is that given a list of non-negative integers, arrange them such that they form the largest number. To solve this problem, sort the array in descending order, but sorting the list/array does not work here.
 
The idea is to use any of the comparison-based sorting algorithms.

Q3. Bridges In A Graph
Given an undirected graph of V vertices and E edges. Your task is to find all the bridges in the given undirected graph. A bridge in any graph is defined as an edge which, when removed, ...read more
Ans. Brute Force
The brute force approach to find all the bridges in a given graph is to check for every edge if it is a bridge or not, by first not considering current edge is not in given graph and then checking if the vertices that it was connecting are still connected or not, using DFS(DepthFirst Search). Given below is an algorithm that will find all bridges in a graph.
 
Algorithm :
1. Initialise a visited array with fa...read more

The interviewer was very friendly. It started at 10:00 AM and lasted for 60 minutes. It was the only technical interview and NO HR interview was there. The video was kept on with screen sharing.

Q1. Sum of Digits
Ninja is given an integer ‘N’. One day Ninja decides to do the sum of all digits and replace the ‘N’ with the sum of digits until it becomes less than 10. Ninja wants to find what will be the...read more
Ans. Brute Force Approach
The main idea is to do the sum of digits until it becomes less than 10.
 
Algorithm:
• Add a condition if N is less than 10 then return N.
• Do the sum of all digits.
• Make a recursive call and pass the sum of digits as N.
• Return the answer which you get from a recursive call.

You are given an integer 'N'. You need to find the sum of squares of the first 'N' natural numbers.
For example:
If 'N' = 4. You need to ...read more
Ans. Brute Force - Recursive
• Write a recursive solution for adding the sum of the squares of the first ‘N’ natural numbers.
• The base case would be the sum of the first natural number, which is 1.
• Sum up the squares of each number from 1 to ‘N’.
• Finally, return this sum.
Space Complexity: O(1)Explanation:
O(N), where ‘N’ is the given number.
