TCS NQT 2021 was a significant milestone for engineering graduates, marking a shift toward more complex, logic-heavy assessments. The recruitment process for both the Ninja and Digital profiles focused heavily on a candidate's ability to handle mathematical patterns, array manipulations, and string processing under tight time constraints. If you are practicing with 2021 past papers, you are likely noticing a trend toward competitive programming standards.
Solution Logic: Iterate through the string. If a character is present in the set of vowels, skip it; otherwise, add it to the result. Tcs Coding Questions 2021
2021 trend: TCS loved problems that mix string indexing and array frequency. TCS NQT 2021 was a significant milestone for
Seating Inefficiency: Calculate the "total inefficiency" based on how people are seated at tables and the resulting arguments, often involving conditional logic or optimization. 2. Core Patterns & Focus Areas Key Topics Example Logic Arrays Rotation, Equilibrium index, Sorting 0s/1s/2s Finding the second largest without full sorting. Strings Palindromes, Anagrams, Frequency counts Finding the most repeating character in a word. Numbers Prime ranges, Armstrong numbers, GCD/LCM Checking if a number is a "Strong" or "Harshad" number. Digital/Prime Dynamic Programming, Matrix rotation, Graphs Rotating a matrix 90 degrees or solving the 0/1 Knapsack. 3. Preparation Resources Solution Logic: Iterate through the string
Note: In some 2021 drives, TCS asked 2 coding questions: one easy (array/string manipulation) and one medium (logic/math/DP).
Example: Input - [1, 2, 3, 4, 5], target sum - 7, Output - 2
