When working with data streams, logs, or financial time-series data, it's often important to detect continuous chunks of values that add up to a specific target. This C# solution is particularly useful when working with time-series arrays in .NET, or...
Problem Description 1695. Maximum Erasure Value This problem asks us to find the maximum sum of a contiguous subarray where all elements are unique (no duplicates). We need to identify the subarray with unique elements that has the largest sum and ...
Ever written a nested loop, stared at your O(n²) time, and whispered “there has to be a better way”? There is. And it’s 🔥. Monotonic Stacks and Queues are those underdog tricks that seem obscure... until they make your entire codebase faster and pre...
Imagine going through a list once and solving a problem that would otherwise need nested loops and a prayer. That’s the magic of Two Pointers and Sliding Windows — algorithms that give you O(n) time for problems that feel like they should be O(n²). I...
Hashmaps. Everyone thinks they’re just glorified phonebooks for storing key: value pairs.But what if I told you they’ve been silently solving some of the trickiest DSA problems…while arrays are still figuring out how not to get O(n) time for everythi...
