Slow Execution: Using inefficient algorithms that timed out on hidden test cases.
The coding section in 2021 typically featured two problems: one of low-to-medium difficulty (Ninja level) and one of high difficulty (Digital level). To help you prepare, let’s dive into the most frequent topics and actual questions that appeared during the 2021 slots. Core Topics for TCS Coding 2021
If you are preparing for an upcoming assessment, let me know which you prefer or what specific topic (like Dynamic Programming or Matrix manipulation) you would like to drill down into next. Share public link
two = (number-5*five-one)/2; System.out.println(one+two+five); System.out.println(five); System.out.println(two); System.out.println(one);
Success in the TCS coding environment requires adherence to their specific compiler infrastructure: C, C++, Java, Python 3, and Perl. Tcs Coding Questions 2021
def solve_vehicles(): try: v = int(input().strip()) w = int(input().strip()) except ValueError: print("INVALID INPUT") return # Check validation boundaries based on rules of wheels and vehicles if (w % 2 != 0) or (w < 2) or (v >= w) or (w < 2 * v) or (w > 4 * v): print("INVALID INPUT") return # Formula derived from linear equations four_wheelers = (w - 2 * v) // 2 two_wheelers = v - four_wheelers print(f"TW = two_wheelers FW = four_wheelers") if __name__ == "__main__": solve_vehicles() Use code with caution. Key Mistakes to Avoid in TCS NQT Platforms

The Ninja role serves as the entry-level software engineering track. In 2021, the coding section typically consisted of: 2 coding questions.
You are given an array of integers. Write a program to check if there are three consecutive even numbers or three consecutive odd numbers in the array. If found, print "True", otherwise print "False". Slow Execution: Using inefficient algorithms that timed out
Success in these exams requires mastery of specific data structures and algorithmic patterns. The 2021 questions were predominantly centered around:
Find an index such that the sum of elements at lower indices equals the sum of elements at higher indices.
TCS test suites heavily verify edge cases. Always handle negative bounds, empty arrays, extreme upper limits, and invalid character strings.
Accept the oxygen levels (integers between 1 and 100) of 3 trainees for 3 rounds (total 9 inputs). Calculate the average oxygen level for each trainee. Core Topics for TCS Coding 2021 If you
One of the 2021 slots required checking whether a given string is a valid token or a reserved keyword in C/C++. Given an array of 16 keywords (e.g., defer , switch , while , case , void , etc.), determine if the input string matches any keyword. Input: while Output: while is a keyword Input: matrix Output: matrix is not a keyword C++ Solution:
Algorithms must complete execution within 1.0 to 2.0 seconds. For arrays of size
: Given an array Arr[ ] of N integers and a positive integer K , the task is to cyclically rotate the array clockwise by K . Note: Keep the first element of the array unaltered. Example :
The majority of the coding problems fell into four major categories:
