10+ Continental Automotive Components Interview Questions and Answers
Q1. Remove Character from String Problem Statement
Given a string str
and a character 'X', develop a function to eliminate all instances of 'X' from str
and return the resulting string.
Input:
The first line contai...read more
Develop a function to remove all instances of a given character from a string.
Iterate through the string and build a new string excluding the specified character.
Use a StringBuilder or similar data structure for efficient string manipulation.
Handle edge cases such as empty string or character not found in the input string.
Q2. Boundary Sum Problem Statement
Given a Binary Tree with 'N' nodes, compute and return the sum of all its boundary nodes. The boundary nodes include the root node, leftmost external nodes, rightmost external nod...read more
The Boundary Sum Problem involves calculating the sum of boundary nodes in a binary tree.
Traverse the tree in a specific order to identify the boundary nodes (root, leftmost, rightmost, and leaves)
Keep track of the sum of these boundary nodes as you traverse the tree
Handle cases where nodes have no children (-1)
Q3. Complete String Problem Statement
Given an array of strings A
of size N
, determine the longest complete string. A string is deemed complete if every prefix of the string also appears in the array. If multiple s...read more
Find the longest complete string in an array of strings, where every prefix of the string also appears in the array.
Iterate through each string in the array and check if all its prefixes exist in the array.
Keep track of the longest complete string found so far, and return the lexicographically smallest one if multiple exist.
If no complete string is found, return 'None'.
Q4. Anagram Pairs Verification Problem
Your task is to determine if two given strings are anagrams of each other. Two strings are considered anagrams if you can rearrange the letters of one string to form the other...read more
Determine if two strings are anagrams of each other by checking if they contain the same characters.
Create character frequency maps for both strings and compare them.
Sort both strings and compare if they are equal.
Use a hash table to store character counts and check if they are the same for both strings.
Q5. Segregate Odd-Even Problem Statement
In a wedding ceremony at NinjaLand, attendees are divided into two groups: bride’s side and groom’s side. Attendees from the bride’s side hold odd numbers, while those from ...read more
Rearrange attendees from bride's side and groom's side while maintaining original order within each group.
Iterate through the linked list and separate odd and even numbers into two separate lists.
Merge the two lists while maintaining the original order within each group.
Output the rearranged linked list with bride's side attendees followed by groom's side attendees.
Q6. Tell me about OOPS - Explain modular code
OOPS is a programming paradigm that uses objects to represent real-world entities. Modular code is code that is divided into separate, independent parts.
OOPS stands for Object-Oriented Programming System
It focuses on creating reusable code and reducing complexity
Modular code is easier to maintain, test, and debug
It involves breaking down code into smaller, self-contained modules
Each module performs a specific task and can be easily replaced or updated
For example, a modular co...read more
Q7. Tell which tech stack you’d use for which case
For web development, I'd use MERN stack. For mobile development, I'd use React Native. For data analysis, I'd use Python stack.
MERN stack (MongoDB, Express.js, React.js, Node.js) for web development
React Native for mobile development
Python stack (NumPy, Pandas, Matplotlib) for data analysis
Consider the project requirements and scalability before choosing a tech stack
Q8. What do you think about affirmative action
Affirmative action is a complex issue with both pros and cons.
Affirmative action can help promote diversity and equal opportunities for underrepresented groups.
However, it can also lead to reverse discrimination and undermine merit-based hiring practices.
Ultimately, the effectiveness of affirmative action depends on how it is implemented and monitored.
For example, some companies may set quotas for hiring certain groups, while others may focus on outreach and training programs...read more
Q9. In which programming language you are good at?
I am proficient in Java and Python.
Strong understanding of object-oriented programming concepts
Experience with Java frameworks such as Spring and Hibernate
Proficient in Python libraries such as NumPy and Pandas
Q10. Write a program to print HCF of numbers as output
Program to print HCF of numbers as output
Take input of two numbers from user
Find the smaller number between the two
Run a loop from 1 to the smaller number
Check if both numbers are divisible by the current loop variable
If yes, update the HCF variable
Print the HCF as output
Q11. explain cloud concepts
Cloud concepts refer to the delivery of computing services over the internet, including storage, databases, networking, and more.
Cloud computing allows users to access and use resources on-demand over the internet.
It provides scalability, flexibility, and cost-efficiency compared to traditional on-premises solutions.
Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.
