5. Real Tech Mahindra Coding Problems with Full Solutions

The SuperCoder coding section features algorithmic challenges requiring optimal time and space complexity. Here are two prominent problems frequently encountered in Tech Mahindra drives:

Coding Problem 1: Group Anagrams Together

Problem Statement: Given an array of strings strs, group the anagrams together in any order. An Anagram is a word formed by rearranging the letters of a different word, using all original letters exactly once.

// Optimal C++ Solution using Hash Map with Sorted Strings as Keys
// Time Complexity: O(N * K log K) | Space Complexity: O(N * K)

#include <iostream>
#include <vector>
#include <string>
#include <unordered_map>
#include <algorithm>

using namespace std;

vector<vector<string>> groupAnagrams(vector<string>& strs) {
    unordered_map<string, vector<string>> groups;
    
    for (const string& s : strs) {
        string key = s;
        sort(key.begin(), key.end());
        groups[key].push_back(s);
    }
    
    vector<vector<string>> result;
    for (auto& pair : groups) {
        result.push_back(pair.second);
    }
    
    return result;
}

int main() {
    vector<string> strs = {"eat", "tea", "tan", "ate", "nat", "bat"};
    auto grouped = groupAnagrams(strs);
    
    for (const auto& group : grouped) {
        cout << "[ ";
        for (const string& s : group) cout << s << " ";
        cout << "] ";
    }
    cout << endl;
    return 0;
}

Coding Problem 2: Longest Consecutive Sequence

Problem Statement: Given an unsorted array of integers nums, return the length of the longest consecutive elements sequence. You must write an algorithm that runs in O(N) time.

// Java Implementation using Hash Set
// Time Complexity: O(N) | Space Complexity: O(N)

import java.util.HashSet;
import java.util.Set;

public class LongestConsecutiveSequence {
    public static int longestConsecutive(int[] nums) {
        if (nums == null || nums.length == 0) return 0;
        
        Set<Integer> numSet = new HashSet<>();
        for (int num : nums) {
            numSet.add(num);
        }
        
        int longestStreak = 0;
        
        for (int num : numSet) {
            // Check if 'num' is the start of a sequence (i.e. num - 1 doesn't exist)
            if (!numSet.contains(num - 1)) {
                int currentNum = num;
                int currentStreak = 1;
                
                while (numSet.contains(currentNum + 1)) {
                    currentNum += 1;
                    currentStreak += 1;
                }
                
                longestStreak = Math.max(longestStreak, currentStreak);
            }
        }
        
        return longestStreak;
    }

    public static void main(String[] args) {
        int[] nums = {100, 4, 200, 1, 3, 2};
        System.out.println("Longest streak: " + longestConsecutive(nums)); // Output: 4 (1, 2, 3, 4)
    }
}

6. Top 12 Tech Mahindra Technical Interview Questions with Answers

The technical interview round lasts 30 to 45 minutes. Expect questions on core computer science subjects, practical coding, database queries, and final-year academic projects:

Q1. What is the difference between Call by Value and Call by Reference?

Answer: In Call by Value, a copy of the actual argument’s value is passed to the formal parameter of the function. Any changes made to the parameter inside the function do not affect the original variable in the caller. In Call by Reference, the memory address (reference) of the actual argument is passed. Any modification inside the function directly updates the caller’s original variable. In Java, all object references are passed strictly by value (i.e. the reference handle itself is copied by value).

Q2. What is the difference between HashMap and Hashtable in Java?

Answer: HashMap is non-synchronized, not thread-safe, allows one null key and multiple null values, and offers superior execution speed in single-threaded environments. Hashtable is legacy, thread-safe (methods are synchronized), does not permit any null keys or values, and introduces performance overhead due to method-level locking. In modern concurrent applications, ConcurrentHashMap is preferred over Hashtable.

Q3. Explain the difference between HAVING and WHERE clause in SQL.

Answer: The WHERE clause filters individual rows before any grouping operations take place; it cannot be used with aggregate functions (e.g. WHERE SUM(salary) > 50000 is invalid). The HAVING clause filters grouped records after the GROUP BY clause has aggregated the rows, and is specifically designed to evaluate aggregate conditions (e.g. HAVING COUNT(*) > 5).

Q4. What is the difference between Process and Thread?

Answer: A process is an independent program running in its own isolated memory address space allocated by the OS. Processes communicate via Inter-Process Communication (IPC). A thread is a lightweight execution unit within a process. Multiple threads of a single process share the same heap memory, code, and data segments, but possess individual program counters and execution call stacks. Thread switching incurs significantly less CPU overhead than process switching.

Q5. What is the Diamond Problem in Multiple Inheritance and how is it solved?

Answer: The Diamond Problem occurs when a class D inherits from two classes B and C, which both inherit from a common base class A. If A contains a method that both B and C override, class D faces ambiguity regarding which method implementation to inherit. C++ resolves this using virtual base classes (class B : virtual public A). Java prevents this altogether by disallowing multiple class inheritance, resolving it safely through Interfaces with explicit default method resolution.

Q6. What are the ACID properties in database management?

Answer: ACID guarantees reliability in transactional systems:
– Atomicity: All statements in a transaction execute completely or none do (“all-or-nothing”).
– Consistency: The database moves only between valid states conforming to all schema rules and constraints.
– Isolation: Concurrent transactions execute independently without mutual interference.
– Durability: Once committed, transaction modifications are permanently persisted even across power failures.

Q7. What is the difference between Abstract Class and Interface?

Answer: An abstract class can have instance fields, constructors, and both concrete and abstract methods with any access modifier. A class can extend only one abstract class. An interface specifies an API contract; variables are implicitly public static final, and methods are public abstract (plus default/static since Java 8). A class can implement multiple interfaces, allowing multiple inheritance of behavior.

Q8. How does Paging work in modern Operating Systems?

Answer: Paging is a memory management scheme that eliminates external fragmentation. It partitions process virtual address spaces into fixed-size blocks called Pages and physical RAM into identically sized blocks called Frames. The Memory Management Unit (MMU) utilizes a Page Table to translate virtual addresses to physical frame addresses. When a referenced page is not present in RAM, a Page Fault interrupt is issued to load the page from disk swap space.

Q9. What is the difference between TCP and UDP?

Answer: TCP (Transmission Control Protocol) is connection-oriented, establishes a 3-way handshake, guarantees in-order packet delivery via acknowledgments, and provides flow/congestion control. It is suited for web browsing (HTTP/HTTPS) and file transfers. UDP (User Datagram Protocol) is connectionless, does not guarantee delivery or packet ordering, and features minimal header overhead. It is ideal for real-time video streaming, VoIP, and online multiplayer gaming.

Q10. What is the difference between Primary Key and Candidate Key?

Answer: A Candidate Key is any column or set of columns that can uniquely identify each tuple in a relation without redundant attributes. A table can have multiple Candidate Keys. The database designer selects one of these Candidate Keys to serve as the Primary Key. The remaining Candidate Keys that are not chosen become Alternate Keys.

Q11. What is the difference between Overloading and Overriding?

Answer: Overloading occurs in the same class where multiple methods have the same name but different signatures (different number, types, or order of parameters). It is resolved at compile-time (static polymorphism). Overriding occurs when a child class redefines a parent class method with the exact same name, return type, and parameters. It is resolved at runtime (dynamic polymorphism) using the virtual method table.

Q12. Explain the difference between BFS and DFS in Graph Traversal.

Answer: BFS (Breadth-First Search) traverses the graph level by level exploring immediate neighbors first, utilizing a FIFO Queue. It finds the shortest path in unweighted graphs. DFS (Depth-First Search) travels as far as possible down each branch before backtracking, utilizing a LIFO Stack or recursion. It is ideal for topological sorting, cycle detection, and maze routing. Both operate in O(V + E) time.
