Kadane's Algorithm: How to Solve Coding Problems Under Pressure
A developer shares how they overcame a timed coding challenge by discovering Kadane's algorithm, which finds the maximum subarray sum in O(n) time. The key insight is to reset the running sum to zero when it becomes negative. This technique reduces a complex problem to a single pass with minimal state.

The article's Jedi metaphor is overblown, but the core lesson—state reduction for efficient algorithms—is a genuinely useful mental model for coding interviews.
