Adjusting for Your Timeline

If you have less than $30$ days:

$2$-week plan: Focus on Hash Map, Two Pointers, Sliding Window, Binary Search, Trees, BFS/DFS, and DP $1$D. Skip advanced patterns. Do $3$ problems per pattern instead of $5$.

$1$-week plan: Cover only Hash Map, Two Pointers, Trees, and DP $1$D. These $4$ patterns appear in over $60$% of interviews. Do $2$ problems each.

If you have more time, add Segment Tree and Topological Sort after completing the $30$-day plan.
