TCS Smart Hiring Coding Questions 2026 | Python Solutions
TCS Smart Hiring Coding Round Preparation Guide 2026-27: 38 Python Questions with Solutions, Edge Cases, and Cheat Sheets for BCA, B.Sc, and B.Voc Freshers. The TCS Smart Hiring coding round is the second elimination stage after the aptitude test, and it decides whether you move to the interview round. Many students clear the aptitude section but fail in coding because they do not practice the right question types or understand TCS-specific input/output formats. The TCS Smart Hiring 2026 coding round typically presents 1-2 coding questions to be solved within 15-20 minutes. Languages allowed are Python, Java, C, and C++. We strongly recommend Python because it requires less code, handles input/output more easily, and has built-in functions that save precious time. This guide covers 38 deep-dive coding questions with complete, clean Python solutions organized into 5 categories. Number Problems include reverse number, palindrome check, Armstrong number, factorial (iterative and recursive), Fibonacci series, prime number check, sum of digits, swap numbers without temp variable, leap year check, GCD/LCM, perfect number, and strong number. Array Problems include sum of array elements, largest and second largest element, array sorting (bubble sort, selection sort, built-in sort), array reversal, remove duplicates, linear search, and frequency count. String Problems include string reversal, string palindrome, character count, vowel and consonant counter, word count, anagram check, and case conversion. Pattern Problems include star patterns (right triangle, pyramid, diamond, inverted), number patterns, and alphabet patterns. Real-World and Ignite Problems include temperature conversion, grade calculator, simple interest/compound interest, and billing system logic. Every solution includes not just the code but also a pro tip, a memory hook to remember the approach, sample input/output, and an explanation of the logic. The guide dedicates an entire section to 20 dirty tricks and edge cases that catch 90% of candidates during the TCS coding round. These include: negative number handling (what if the input is -123?), leading zeros (what if input is 007?), empty string edge case, integer overflow for large numbers, off-by-one errors in loops, infinite loop traps, wrong data type casting (int vs float), boundary conditions (0, 1, empty array), whitespace in string input, newline character issues, and more. Knowing these edge cases before the exam means your code passes hidden test cases that most students fail on. The 6 cheat sheets provide quick-reference cards for Python input patterns (the 6 standard ways TCS formats input), Python string methods (split, strip, join, replace, find, count, upper, lower, isdigit, isalpha), Python list/array methods (append, pop, sort, reverse, index, count, slicing), number tricks (modulo, integer division, digit extraction), common algorithm patterns (two-pointer, frequency map, accumulator), and a debugging checklist. The Exam Day Battle Plan provides a minute-by-minute strategy: read both questions first (1 minute), identify the easy question (30 seconds), solve the easy question with all edge cases (5-7 minutes), attempt the harder question (7-10 minutes), debug using the checklist (2 minutes), and submit. The TCS Smart Hiring coding round uses an online IDE with auto-evaluation against hidden test cases. You get partial scoring — so even an incomplete solution earns marks. This is why understanding input format is critical: if your code cannot even read the input correctly, you score zero. The free edition covers the top 20 most repeated questions in 13 pages — perfect for a quick overview if your exam is tomorrow. The complete edition provides all 38 questions, 20 dirty tricks, 6 cheat sheets, and the battle plan in 58 pages — comprehensive preparation for anyone serious about clearing the coding round. This guide is used by over 1,000 BCA and B.Sc students preparing for TCS Smart Hiring 2026-27. The coding patterns repeat every year, so mastering these 38 questions covers 95% of what TCS can ask. Whether you are a Python beginner or intermediate, this guide is structured for you.

Frequently Asked Questions about TCS Smart Hiring Coding
What programming language is used?
All solutions are in Python, which is the recommended language for TCS coding rounds due to its simplicity and speed. Python lets you write solutions faster, handle input easier, and has built-in functions that save time. The logic concepts apply to any language.
Is this updated for 2026?
Yes! Updated with the latest question patterns observed in recent TCS Smart Hiring batches for the 2026-27 recruitment cycle. We track every exam and update the content.
What's the difference between Free and Complete Edition?
The Free Edition covers the top 20 most repeated questions (13 pages) — great for a quick overview. The Complete Edition has 38 deep-dive questions, 20 dirty tricks, 6 cheat sheets, memory hooks, interview prep, and a full exam-day battle plan (58 pages) — total preparation.
Can I download the paid PDF?
The paid edition is available as a secure view-only PDF. You get lifetime access and can view it anytime from your account on any device.
Is the payment secure?
Yes, all payments are processed securely through Razorpay, India's leading payment gateway. We support UPI, debit/credit cards, net banking, and wallets.
What if my payment fails but money is deducted?
The amount will be auto-refunded within 5-7 business days. You can also contact our support for faster resolution.
I'm a complete beginner in Python. Will this help?
Yes! The guide assumes basic Python knowledge (variables, loops, functions). Each solution is written in simple, readable Python with comments explaining every step. The input patterns section alone will save you hours of confusion.

How to Crack TCS Smart Hiring Coding Round 2026
- Master the 6 Python Input Patterns Used by TCS: Learn the 6 standard input templates used in every TCS Smart Hiring coding question: single integer input, array/list input on one line, T test cases format, string input with spaces, matrix/2D input, and multiple separate line inputs. Getting input wrong means zero marks even if your logic is correct.
- Solve All 38 Core Coding Questions by Category: Practice every question type systematically: Number Problems (reverse, palindrome, Armstrong, factorial, Fibonacci, prime, GCD, digit sum), Array Problems (sum, sort, search, max, second-max, duplicates), String Problems (reverse, palindrome, vowels, word count, anagram), Pattern Problems (star, number, alphabet), and Real-World Problems (temperature, grade, interest).
- Memorize the 20 Dirty Tricks and Edge Cases: Study the 20 traps that cause wrong answers on hidden test cases: negative numbers, leading zeros, empty inputs, integer overflow, off-by-one loops, wrong data types, boundary values (0, 1, empty array), whitespace issues, and newline problems. Knowing these before the exam is the difference between partial and full marks.
- Print and Revise the 6 Cheat Sheets: Use the quick-reference cards for Python input patterns, string methods, list operations, number tricks, common algorithm patterns, and the debugging checklist. These are designed for 10-minute revision right before the exam.
- Execute the Exam Day Battle Plan: Follow the proven minute-by-minute strategy: read both questions first (1 min), solve the easy one with edge cases (5-7 min), attempt the harder one (7-10 min), debug with the checklist (2 min), submit. Remember: partial scoring means even incomplete solutions earn marks.
