Tcs Coding Questions 2021 -

Analysis of TCS NQT Coding Questions (2021) The 2021 TCS National Qualifier Test (NQT) coding section was characterized by a shift toward assessing fundamental problem-solving efficiency and precision in handling standard input/output. The questions generally ranged from easy to moderate difficulty, focusing heavily on mathematical series, string manipulation, and array-based logic. 1. Exam Structure and Pattern

The 2021 NQT coding section typically followed a two-question format within the advanced section of a 190-minute total examination. Candidates were often given one simple question (approx. 15-20 minutes) and one more complex algorithmic question (approx. 30 minutes). Supported Languages: C, C++, Java, Python 2.7, and Perl. Evaluation: Based on both public and private test cases.

Key Requirement: Strict adherence to output formats, including no leading/trailing spaces and specific precision for floating-point numbers. 2. Frequently Recurring Question Themes

Based on 2021 slot analyses, questions were primarily drawn from these core areas:

The 2021 TCS National Qualifier Test (NQT) coding paper typically featured two questions, ranging from easy array manipulation to intermediate dynamic programming, within a 45-60 minute timeframe. Common topics included string character counting, series generation (mixed powers of 2 and 3), and coordinate geometry, according to PrepInsta and TakeUForward. You can explore the full, detailed archives of these 2021 solved papers on PrepInsta.

The TCS National Qualifier Test (NQT) in 2021 followed a specific pattern where candidates were typically given two coding questions of varying difficulty levels

. The primary categories for these questions include array manipulation, string processing, and number theory. takeuforward 1. Exam Pattern & Syllabus (2021)

The coding section is usually divided into two parts based on the targeted role (Ninja or Digital/Prime): Great Learning Foundation Coding:

1 question to be solved in 15–30 minutes, focusing on basic logic and data types. Advanced Coding: Tcs Coding Questions 2021

2 questions with a shared time limit of 90 minutes, requiring knowledge of advanced data structures and algorithms. Allowed Languages: C, C++, Java, Python, and Perl. 2. Most Asked Coding Questions in 2021

Based on previous year papers, the following are common problem statements: Key Problem Types Second smallest/largest, rotation by , symmetric pairs, max product subarray.

Palindromes, vowel/consonant count, first non-repeating character, partitioning strings. Number Theory

Prime/Armstrong/Harshad numbers, GCD/LCM, Fibonacci series, base conversion. Scenario-Based

Problems like "Washing Machine" (time calculation based on weight) or "Oxygen Level" (comparing trainee performance). 3. Sample Logic (Unique Digit Counter) Count numbers with non-repeating digits in range

Iterate through the range, convert each number to a string, and check if the count of unique characters equals the total character count. 4. Key Preparation Resources (Most Asked) TCS NQT Coding Questions and Answers 2021

In 2021, the TCS NQT (National Qualifier Test) featured a coding section primarily focused on fundamental algorithms, string manipulation, and array processing. For the 2021 hiring cycles (including the October 2020 and September 2021 slots), the coding round typically consisted of 1 to 2 questions with a time limit ranging from 30 to 45 minutes depending on the specific exam version (Ninja vs. Digital).

Problem 2: Find the Greatest of Three Numbers Using Ternary Operator

Difficulty: Easy
Marks: 10

Statement:
Write a program that takes three integers as input and prints the greatest among them. You must use the ternary operator only (no if-else or built-in max functions).

Constraints:
-10⁹ ≤ numbers ≤ 10⁹

Input format:
Three space-separated integers.

Output format:
Single integer.

Sample Input:
12 45 33

Sample Output:
45

Question 4: Character Shift (Caesar Cipher Lite)

Problem Statement: Accept a string and an integer K. Shift every character in the string K positions forward in the alphabet. (Assume the string contains only lowercase alphabets). If the shift goes past 'z', wrap around to 'a'. Problem 2: Find the Greatest of Three Numbers

Input:

Output:

Example:

Input: abc 2 Output: cde

Solution (Python):

S = input().strip()
K = int(input())
res = ""
for char in S:
    # ASCII logic: 'a' is 97. Subtract 97 to get 0-25 range.
    # Add K, take modulo 26 to wrap around, add 97 back.
    new_char = chr(( (ord(char) - 97 + K) % 26) + 97)
    res += new_char
print(res)

Print first half (Ascending)

for i in range(mid): print(arr[i], end=" ")

The 2021 Exam Pattern (Coding Section)

Before diving into the questions, let's revisit the structure. The TCS NQT 2021 had two mandatory rounds where coding was tested:

  1. Foundation Level (Ninja): Easier, focusing on loops, conditionals, and basic data structures.
  2. Advanced Level (Digital): Harder, requiring knowledge of dynamic programming, recursion, and data structure optimization.

Key Constraints (Typical for 2021):

Most students reported that solving the previous year’s questions (2021) guaranteed at least a 50% score in the coding section.
