3. High-Frequency TCS Coding Questions 2021 (With Logic & Code)

Ensure you can calculate whether your code will run within the standard 1–2 second limit for an array size of 10510 to the fifth power

In the TCS NQT (Ninja and Digital roles), the coding section has specific constraints you must know before writing a single line of code.

Example:

Easy Marks: 10

Below are some of the most frequently reported coding questions from the 2021 slots, along with optimized solutions in Python and C++. Question 1: The Sweet Jar / Candies Problem (Easy)

def solve_vehicles(v, w): # Constraint validation if w % 2 != 0 or w < 2 or v >= w: return "Invalid Input" # System of equations solution # 2x + 4y = w and x + y = v -> 2v + 2y = w -> 2y = w - 2v y = (w - 2 * v) // 2 x = v - y if x >= 0 and y >= 0: return f"TW = x FW = y" else: return "Invalid Input" # Driver Code if __name__ == "__main__": try: v = int(input()) w = int(input()) print(solve_vehicles(v, w)) except ValueError: print("Invalid Input") Use code with caution.

Language Choice: C++ and Java are preferred for their speed, but Python is excellent for string manipulation and handling very large integers (common in TCS "Series" questions).

Code must read purely from standard input ( stdin ) and write directly to standard output ( stdout ). Extraneous prompt texts like print("Enter value: ") will cause the test cases to fail automatically.

Get comfortable coding on platforms that simulate the TCS environment, ensuring you can write code cleanly without the safety net of comprehensive auto-complete IDEs. If you'd like to prepare further for your exam, tell me:

private static boolean isPalindrome(String s, int left, int right) while (left < right) if (s.charAt(left) != s.charAt(right)) return false; left++; right--; // Logic to find prime factors for(i =

for(int i = 0; str[i] != '\0'; i++) if(freq[str[i]] > max) max = freq[str[i]];

Problem Description: A faulty program stores username and password as a continuous string. Extract only letters and special characters—display letters first, then special characters.

n = int(input()) print(find_nth_term(n))
