The 2021 question bank heavily favored problem-solving over syntax memorization. The distribution of questions leaned on the following core domains:

coins. Find the number of ways to pick one coin from each such that their product is an even number Quick Logic: A product is even if at least one of the numbers is even. Total Ways

Selection of trainees for a fitness test depends on their oxygen levels. Three trainees undergo running tests for 3 rounds. The oxygen level of each trainee is measured after each round.You are given the oxygen levels of all 3 trainees for all 3 rounds (total 9 inputs consecutively: Trainee 1 Round 1, Trainee 2 Round 1, Trainee 3 Round 1, Trainee 1 Round 2, etc.).Calculate the average oxygen level for each trainee. Find the fittest trainee(s) with the highest average oxygen level.

Remove all characters except alphabets from a given string. 3. Solved Examples from TCS NQT 2021 Example 1: TCS NQT 2021 Candy JAR Problem

An international organization defines a "Prime Minister" number as a positive integer greater than 10 that satisfies two conditions:

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'. : Focused on basic data structures, arrays, strings,

If any trainee's average oxygen level is below 70, declare them unfit. If all trainees have an average below 70, output "All trainees are unfit". Input Format

Wait – clarify: Better example: arr = [1, 2, 3, 4, 3], K = 6 Pairs: (2,4) and (3,3) → 2 pairs.
