Top 5 TCS CodeVita Coding Questions & Solutions 

Here’s a look at some example coding questions that freshers can expect in TCS CodeVita. Solving such problems will help improve your chances of performing well in the competition.

Problem Statement 1

Steve is participating in competitive coding. Whenever he makes a submission at time 't', any submission made exactly 5000 seconds before 't' is removed from the queue.

Given N submissions, where each submission is associated with a distinct time 't', determine the maximum size of the submission queue at any point in time after all 'N submissions.

Note: It is guaranteed that every submission uses a strictly larger value of ‘t’ than the previous submission.

Input Format

The first line of input contains an integer N representing the size of the array, which is the number of submissions.

The second line contains N space-separated integers representing the array arr, which contains the timestamps of each submission.

Output Format

Print an integer in a single line containing the maximum size possible.

Constraints

1 <= N <= 10^5

1 <= arr[i] <= 10^8

Solution C++

Solution Java

Solution Python

Problem Statement 2

There are N suns in a galaxy, each sun has M planets, each of the M planets have some number of moons, denoted by galaxy(i)(j), where galaxy(i)(j) denotes the number of moons of the jth planet having the ith sun.

Your task is to determine the maximum number of moons in any solar system. For each sun, calculate the total number of moons across all its planets and output the highest total number of moons found in a single solar system.

Input Format

The first line of input contains two space-separated integers, N and M, representing the number of suns and the number of planets per sun, respectively.

The next N lines of input contain M space-separated integers, representing the number of moons for each planet around the respective sun.

Output Format

Display a single integer denoting the maximum total number of moons in a solar system (i.e., across all planets orbiting the same sun).

Constraints

1<=N<=5*10^2

1<=M<=5*10^2

1<=galaxy(i)(j) <=10^4

Solution C++

Solution Java

Solution Python

Problem Statement 3

A toy manufacturing factory produced N toys in a day. The manager has a list of product IDs and another list containing the sizes of the corresponding toys, each of length N. In other words, the i-th integer in the product IDs list represents the product ID of the i-th toy, and the i-th integer in the sizes list represents the size of the i-th toy.

However, the manager accidentally combined these lists by placing the product IDs list in front of the sizes list, resulting in a single list of 2N elements.

You are an employee, and the manager wants you to recover the data and present it as another list of 2N elements such that the product ID of each toy is followed by its size.

Input Format

The first line of the input contains a single integer N, representing the number of toys produced.

The second line contains 2*N space-separated integers representing the merged list given to you by the manager.

Output Format

Print 2*N space-separated integers representing the list wanted by the manager

Constraints

1 <= N <= 10^5

1 <= ai, bi<= 10^2

Solution C++

Solution Java

Solution Python 

Problem Statement 4

Steve is participating in competitive coding. Whenever he makes a submission at time 't', any submission made exactly 5000 seconds before 't' is removed from the queue.

Given N submissions, where each submission is associated with a distinct time 't', determine the maximum size of the submission queue at any point in time after all 'N submissions.

Note: It is guaranteed that every submission uses a strictly larger value of ‘t’ than the previous submission.

Input Format

The first line of input contains an integer N representing the size of array which is number of submissions.

The second line contains N space separated integers representing the array arr which contains the timestamps of each submission.

Output Format

Print an integer in a single line containing the maximum size possible.

Constraints

1 <= N <= 10^5

1 <= arr[i] <= 10^8

Solution C++

Solution Java

Solution Python 

Problem Statement 5

One day, Jack finds a string of characters. He is very keen to arrange the characters in reverse order, i.e., first characters become the last characters, second characters become the second-last characters, and so on. Now, he wants your help to find the kth character from the new string formed after reversing the original string.

Note: String contains only lowercase Latin letters.

Input Format

The first line contains two integers n, k — the length of array and the value of k respectively.

The second line contains a string containing n characters.

Output Format

Print a single line containing the kth character of the string.

Constraints

1 ≤ k ≤ n≤ 10^6

Solution C++

Solution Java

Solution Python
