Problem Statement:
You have to design a weekly exercise summary by taking the number of minutes of daily exercise for 7 consecutive days.
The exercise duration for all days will be entered by the user.

Your task is to:

1. Calculate the total exercise duration for the week
2. Calculate the average daily workout duration (rounded to nearest integer)

Input Format:

Day 1 exercise duration: <minutes> Day 2 exercise duration: <minutes> ... Day 7 exercise duration: <minutes> 

Output Format:

Exercise summary Total exercise duration : <total> (minutes) Average daily exercise duration: <average> minutes 

Example Input:

Day 1 exercise duration: 45 Day 2 exercise duration: 15 Day 3 exercise duration: 30 Day 4 exercise duration: 15 Day 5 exercise duration: 5 Day 6 exercise duration: 10 Day 7 exercise duration: 20 

Example Output:

Exercise summary Total exercise duration : 140 (minutes) Average daily exercise duration: 20 minutes 

Solution (Java):

import java.util.Scanner;

public class ExerciseSummary {

        Scanner scanner = new Scanner(System.in);
        int[] exerciseDuration = new int[7];
        int total = 0;
        
        for (int i = 0; i < 7; i++) {
            System.out.print("Day " + (i + 1) + " exercise duration: ");
            exerciseDuration[i] = scanner.nextInt();
            total += exerciseDuration[i];
        }
        
        double average = total / 7.0;
        average = Math.round(average * 100.0) / 100.0;
        
        System.out.println("Exercise Summary");
        System.out.println("Total exercise duration: " + total + " minutes");

• N is the upper limit

Your task is to find all palindrome numbers in the range and return the count of such numbers.

Input Format:

Enter M : <lower limit integer> Enter N : <upper limit integer> 

Output Format:

<number of palindrome numbers> 

Definition:
A palindrome number is a number that reads the same backward as forward.
Example: 121, 131, 11, 9

Example Input:

Enter M : 10 Enter N : 20 

Example Output:

1 

Explanation:
Only one palindrome exists between 10 and 20 → 11

Solution (C++):

#include <iostream>
using namespace std;

bool isPalindrome(int number) {
    if (number < 0) return false;
    int original = number, reversed = 0;
    while (number > 0) {
        reversed = reversed * 10 + number % 10;
        number /= 10;
    }
    return original == reversed;
}

int main() {
    int M, N;
    cout << "Enter M: ";
    cin >> M;
    cout << "Enter N: ";
    cin >> N;
    int count = 0;
    for (int i = M; i <= N; i++) {
        if (isPalindrome(i)) count++;
    }
    cout << count << endl;
    return 0;
}

Question 3: Train Travel Time
Problem: A train covers 800 meters (400m track + 400m bridge) at a given speed (km/hr). Calculate the time taken in seconds using the formula: (Total distance / Speed) * (18/5).

Solution (C++):

#include <iostream>
using namespace std;

int main() {
    double speed;
    cin >> speed;
    int totalDistance = 800;
    double speedMs = speed * 5.0 / 18.0; // Convert km/hr to m/s
    int time = totalDistance / speedMs;
    cout << time << endl;
    return 0;
}

Question 4: Split Array with Equal Averages
Problem: Given an array of integers, check if it can be split into two subarrays with equal averages. Output true or false.

import java.util.Scanner;

public class ArraySplit {
    public static boolean canSplit(int[] arr, int n) {
        int totalSum = 0;
        for (int i = 0; i < n; i++) totalSum += arr[i];
        int leftSum = 0;
        for (int i = 0; i < n - 1; i++) {
            leftSum += arr[i];
            int rightSum = totalSum - leftSum;
            if (leftSum * (n - i - 1) == rightSum * (i + 1)) return true;
        }
        return false;
    }

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        int[] arr = new int[n];
        for (int i = 0; i < n; i++) arr[i] = sc.nextInt();
        System.out.println(canSplit(arr, n) ? "true" : "false");
        sc.close();
    }
}

Tips for TCS NQT Success

• Practice Input Handling: Many questions use Scanner (Java) or cin (C++). Test with sample inputs to avoid errors.
• Master Arrays and Strings: Most problems involve arrays or string manipulation. 
• Understand Math Basics: Questions like Train Travel Time and Speed Calculation require unit conversions. Brush up on formulas!
• Learn HashMaps: The Inventory Frequency Counter uses a HashMap, which is super common in coding tests.
• Test Edge Cases: For example, in the Jump Game, check if an array with one element or zeros works correctly.
• Time Management: TCS NQT has tight time limits. Solve easier problems first, then tackle complex ones like Jump Game.

• 3 ≤ n ≤ 1000
• -1000 ≤ arr[i] ≤ 1000

Example 1:

Input: 5 -3 7 8 1 0 Output: 56 

Explanation:
Maximum product = 7 × 8 × 1 = 56

Example 2:

Input: 5 -3 -2 4 8 1 Output: 64 

Explanation:
Maximum product = (-3) × (-2) × 8 = 48
Also try 4 × 8 × 1 = 32
But (-3 × -2 × 8) = 48
Correction: Actually (-3 × -2 × 8) = 48
Typo in the image: 64 is incorrect unless the array is different.

Key Insight:

• To get the maximum product, consider:
  1. The product of the 3 largest numbers
  2. The product of the 2 smallest (most negative) numbers and the largest number
