TCS CodeVita Previous Year Questions with Answers
Reviewing previous year’s questions is one of the most effective ways to prepare for TCS CodeVita. Here’s a look at some commonly asked questions and their solutions:
|
Previous Year Question |
Solution |
|
"Find the smallest missing positive integer from an unsorted array." |
Solution: Use a hash set to track the elements, then iterate through the array to find the smallest missing integer. |
|
"Given a string, write a function to check if it is a palindrome." |
Solution: Reverse the string and compare it with the original. |
|
"Implement an algorithm to find the longest common subsequence (LCS)." |
Solution: Dynamic programming is used to solve this problem by constructing a 2D array to store the lengths of common subsequences. |

Top 5 TCS CodeVita Questions with Answers
Problem Statement 1
Assert whether the given string has all the letters of the English alphabet or not.
If yes return "True" else return "False".
Assume the string contains nothing but lowercase English letters.
Input Format
The string to be checked.
Output Format
Display "True" if all the letters in English alphabets are present else display "False".
Note: Output is case-sensitive.
Constraints
1<=|S|<=1e^5
Solution C++
Solution Java
Solution Python
Problem Statement 2
You are provided with a 2D array(N*M). Your task is to create an ArrayList of Node objects, where each row of the 2D array corresponds to one entry in the ArrayList. After that, a doubly-linked list is constructed, arranging nodes first by even indices from the ArrayList, followed by the odd indices.
Input Format
The first line contains an integer N, representing the size of the array row.
The second line contains an integer M, representing the size of array col.
The third line contains an array.
Output Format
return the linked list
Constraints
1 <= N < 10^2
1 <= M < 10^2
Solution C
Solution Python
Solution Java
Problem Statement 3
You're in a world where magical creatures engage in a peculiar contest, and you've been entrusted with keeping track of the matches.
The rules are as follows:
If there is an even number of creatures, they form pairs, and a total of n/2 matches are played. The victors of these matches advance to the next round. When there's an odd number of creatures, an intriguing twist unfolds.
One of them is granted a special power and advances directly to the next stage, while the remaining creatures pair off for matches. The number of matches in this scenario is (n - 1)/2. The creature with the special power joins the winners of these matches in the next round.
Your mission is to determine the overall number of matches that take place in this magical contest until a single champion emerges. How many matches will be required to decide the ultimate winner?
Input Format
An integer n represents the initial number of magical creatures in the contest.
Output Format
An integer represents the total number of matches played in the magical contest until a single champion is determined.
Constraints
1 <= n <= 200
Solution C++
Solution Java
Solution Python
Problem Statement 4
You are a shopkeeper and bought N pairs of socks of several colours in bulk. The colour of each pair of socks is represented as a non-negative integer. The socks are sold as sets of 3 each. A set of socks consists of 3 socks of the same colour.
You want to find the number of different sets that can be made from the N pairs of socks you bought today.
Note: The order of indices of sock pairs in the set does not matter.
Input Format
The first line of the input contains a single integer N which denotes the number of pairs of socks that you have.
The second line of the input contains n space-separated integers a1, a2, …, an, where ai represents the colour of the ith pair.

Solution C++
Solution Java
Solution Python
Problem Statement 5
