I Tried to Escape LeetCode for 2 Years (But Here We Are)

Short summary

After a two-year hiatus, the author returns to LeetCode armed with a deliberate strategy: master fundamentals, learn algorithm patterns (two-pointers, sliding window, fast/slow), then practice with intent. Key advice: think before coding, verify edge cases, document solutions, and prioritize time complexity understanding. The core insight: shifting from mindless grinding to pattern-based, deliberate learning transforms DSA mastery and interview success.

• •Master fundamentals and C++ STL before grinding LeetCode problems
• •Learn algorithm patterns (two-pointers, sliding window) to identify problem types
• •Shift from mindless grinding to deliberate learning—understand mistakes, verify edge cases, document solutions
