Key Recommendations

  • Focus on understanding concepts rather than memorizing syntax
  • Practice coding daily - at least 1 hour of hands-on coding
  • Build small projects to reinforce learning
  • Review previous topics regularly to retain knowledge
  • Participate in coding challenges (LeetCode, HackerRank)
Problem solving guide

Comprehensive C++ Problem-Solving Learning Path

This 18-week C++ problem-solving roadmap on Nikhil Learn Hub guides students, competitive programmers, and interview candidates through data structures and algorithms with weekly topics, practice hours, and must-solve problems. Learn C++ problem solving step by step with algorithms, coding practice, logical thinking, and interview preparation guidance.

Learning DSA in C++ builds patterns you will reuse in technical screens and timed contests. If you are new to C++, start with our C++ tutorial before the 18-week DSA schedule.

Foundation (Weeks 1–8)

  • Basics, control flow, functions, and recursion
  • Arrays, strings, and core linear structures
  • Language-specific memory or collection patterns
  • Linked lists, stacks, and queues

Algorithms (Weeks 9–18)

  • Trees, graphs, sorting, and searching
  • Bit manipulation and divide & conquer
  • Greedy algorithms and dynamic programming
  • Backtracking and combinatorial search

Who Should Follow This Roadmap

Engineering students and developers who want an interview-ready C++ DSA plan benefit most from this schedule.
