📖 TCS NQT 2025 Coding Questions with Solutions

1️⃣ Sum of Integers in a Range

📜 Problem Statement: Given a range [m, n] (both inclusive) where 0 <= m, n <= 10000, find the sum of all integers between m and n.

📝 Example:

Input:
0 3
Output:
6
Explanation:
0+1+2+3 = 6

🔹 Solution in Java:

import java.util.Scanner;

public class SumInRange {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int m = scanner.nextInt();
        int n = scanner.nextInt();
        scanner.close();

        int sum = 0;
        for (int i = m; i <= n; i++) {
            sum += i;
        }
        System.out.println(sum);
    }
}

🐍 Solution in Python:

# Read input
m, n = map(int, input().split())

# Calculate sum
result = sum(range(m, n + 1))

# Print result
print(result)

2️⃣ Minimum Team Selection to Cover Required Skills

📜 Problem Statement: You are given a list of required skills and a list of candidates, where each candidate has a subset of skills. Your task is to find the smallest possible team such that all required skills are covered.

📝 Example:

Input:
a b c d
4
a b
b c
c d
d
Output:
0 2

🔹 Solution in Java:

import java.util.*;

public class MinimumTeamSelection {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        String[] requiredSkills = scanner.nextLine().split(" ");
        int n = scanner.nextInt();
        scanner.nextLine();

        List<Set<String>> candidates = new ArrayList<>();
        for (int i = 0; i < n; i++) {
            Set<String> skills = new HashSet<>(Arrays.asList(scanner.nextLine().split(" ")));
            candidates.add(skills);
        }
        scanner.close();

        List<Integer> result = findMinimumTeam(requiredSkills, candidates);
        for (int index : result) {
            System.out.print(index + " ");
        }
    }
}

🐍 Solution in Python:

from itertools import combinations

def find_minimum_team(required_skills, candidates):
    skill_to_index = {skill: i for i, skill in enumerate(required_skills)}
    n = len(candidates)
    skill_sets = []
    
    for candidate in candidates:
        skill_mask = 0
        for skill in candidate:
            if skill in skill_to_index:
                skill_mask |= (1 << skill_to_index[skill])
        skill_sets.append(skill_mask)
    
    m = len(required_skills)
    min_team = None
    
    for size in range(1, n + 1):
        for team in combinations(range(n), size):
            team_mask = 0
            for i in team:
                team_mask |= skill_sets[i]
            if team_mask == (1 << m) - 1:
                min_team = team
                return list(min_team)
    
    return []
