Matches system strings exactly. Extra spaces or missing newlines can fail hidden test cases.

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

Given a number (up to 100 digits), find the absolute difference between the sum of digits at odd positions and even positions. Key Strategy: Handle Large Input : Since the number can have 100 digits, read it as a Tcs Coding Questions 2021

Series generation, prime number algorithms (Sieve of Eratosthenes), base conversions, and matrix operations.

s = input().split() res = [] for word in s: if len(word) % 2 == 0: res.append(word[::-1]) else: res.append(word) print(' '.join(res)) Matches system strings exactly

Input: [11, 23, 41, 29, 56] Output: 3 (Because 11→1+1=2(prime), 23→2+3=5(prime), 41→4+1=5(prime), 29 is prime but 2+9=11(prime) actually also qualifies—so 4? Wait: 56 is not prime. So output is 4). Subtract 97 to get 0-25 range

Before diving into specific questions, you must understand the battlefield.

In 2021, the TCS NQT coding section underwent specific structural updates to better evaluate logical thinking and foundational programming concepts. : 2 Questions.
