What I learned after solving 100 Leetcode Problems

Short summary

Author completed 100 LeetCode problems in 4 days and identified five core DSA patterns underlying 60% of problems. Key lessons: master fundamentals first, solve naively then optimize, study editorials, and reinforce basics with easy problems—all habits that improve problem-solving across domains.

• •60% of LeetCode problems share core algorithmic patterns (two-pointers, sliding window, binary search, DP)
• •Internalize approaches over memorizing code; start with naive solutions then optimize
• •Never skip easy problems—they reinforce fundamentals that medium/hard problems depend on
