DAY 26/250
DAY 26/250
This problem isn’t about memorizing symbols. It’s about spotting when subtraction breaks the left-to-right rule.
DAY 25/250
DAY 25/250
This problem looks like string manipulation, but interviews test whether you understand nesting depth, not stacks.
DAY 24/250
DAY 24/250
This problem isn’t about joining strings. It’s about comparing characters lazily without wasting memory.
DAY 23/250
DAY 23/250
This problem isn’t about matching characters. It’s about preserving structure while enforcing one-to-one mappings.
DAY 22/250
DAY 22/250
This problem looks like greedy picking, but the real trick is sliding the choice from one side to the other.
DAY 21/250
DAY 21/250
This problem isn’t about flipping zeros. It’s about keeping a valid window while allowing controlled violations.
DAY 20/250
DAY 20/250
This problem isn’t about substrings. It’s about shrinking the window at the right time to protect uniqueness.
DAY 19/250
DAY 19/250
This problem isn’t about removing intervals. It’s about keeping the right ones so overlaps disappear naturally.
DAY 18/250
DAY 18/250
This problem isn’t about merging ranges. It’s about sorting first and knowing exactly when two intervals overlap.
DAY 17/250
DAY 17/250
This problem isn’t about sorting. It’s about finding sequence starts and expanding only when it’s logically safe.
DAY 16/250
DAY 16/250
This problem looks like multiplication, but interviews test whether you can break dependency using prefix and suffix products.
DAY 15/250
DAY 15/250
This problem isn’t about sorting numbers. It’s about grouping by frequency and pulling answers efficiently.
DAY 14/250
DAY 14/250
This problem isn’t about grouping strings. It’s about designing a reliable key that represents character frequency.
DAY 13/250
DAY 13/250
This problem isn’t about rearranging strings. It’s about counting correctly and failing fast when characters don’t match
DAY 12/250
DAY 12/250
This problem isn’t about comparing arrays. It’s about using hashing correctly to ensure uniqueness without extra passes.
DAY 11/250
DAY 11/250
This problem is not about counting 1s. It’s about knowing exactly when to reset and when to record your result.
DAY 10/250
DAY 10/250
This problem is not about averages. It’s about fixing a window and updating sums efficiently instead of recalculating everything.
DAY 9/250
DAY 9/250
Most people memorize this problem. Interviews expect you to explain where water comes from at every index.
DAY 8/250
DAY 8/250
This problem is not about buying and selling stocks. It’s about tracking the minimum so far and making one correct decision.
DAY 7/250
DAY 7/250
This problem isn’t about counting frequencies. It’s about canceling elements until only the true majority survives.
DAY 6/250
DAY 6/250
DAY 5/250
