Tcs Coding Questions 2021 Guide

If you are searching for , you are likely preparing for the TCS NQT (National Qualifier Test) or the TCS Ninja/Digital hiring rounds. Although 2021 was a few years ago, those questions remain a goldmine of practice. Why? Because TCS recycles logic. The syntax of the language may change, but the algorithmic patterns—arrays, strings, greedy algorithms, and mathematical puzzles—remain timeless.

"1001" → Choose substring indices 1 to 3 ("001")? Actually original: 1 0 0 1. Pick substring positions 2-4 (0,0,1) has only one '1'. Not allowed. This was so tricky that TCS 2021 actually had a simpler version: Count the number of groups of consecutive '1's. Tcs Coding Questions 2021
