FAQs

What makes Specialist Programmer different from other roles in the roadmap?

It emphasizes hard DSA (DP, graphs, trees, advanced algorithms) plus a competitive programming mindset, with coding problem mix focused more on DSA than aptitude.

Which topics are covered in the first 1-2 months?

The plan includes programming mastery with a C++ STL deep dive (or Java alternatives), then a basic DSA foundation covering arrays/strings, two pointers & sliding window, prefix sums and Kadane’s algorithm, and basic recursion with practice sets.

How does the roadmap guide competitive programming preparation?

It recommends solving specific contest types on Codeforces, CodeChef, LeetCode weekly contests, and AtCoder beginner contests, with a practice strategy of participating multiple times per week, upsolving, learning editorials, and timing each problem.
