dev.to published an article on 6 October 2026 titled "Mastering Monotonic Stacks: Next Greater Element and Histogram Problems." The piece details how developers can process sequential data more efficiently by using a specialized data structure called the Monotonic Stack. This approach reduces time complexity from $O(N^2)$ to an optimal $O(N)$ by leveraging a popping invariant where elements are pushed and popped at most once.
The article illustrates these concepts using classic problems such as Daily Temperatures and Largest Rectangle in Histogram. For temperature data, a monotonic decreasing stack helps find the next greater element for each index. In histogram scenarios, a monotonic increasing stack identifies boundaries formed by shorter bars to the left and right.
The author notes that monotonic stacks are an indispensable tool that shifts perspective from brute-force scanning to maintaining structural invariants. This method allows quadratic complexity problems to drop cleanly into linear time for software engineers. The report concludes by encouraging readers to practice identifying these invariants in boundary problems.
How the market reacted
Whalio's own Binance spot order flow for STX, measured when this story was written up on 6 October 2026. Not the outlet's figures.
STX is trading at $0.3792 with a 1-hour buy ratio of 66.1% against a 4-hour ratio of 44.8%. Short-term buying pressure is significantly stronger than the broader 24-hour average of 55.2%, indicating a recent surge in demand. The 1-hour volume delta is positive at +$17,900, contrasting with a negative -$17,250 delta over the 4-hour window. This suggests that immediate buying activity is outpacing selling pressure in the current hour. Over the last 24 hours, the volume delta stands at +$251,972 with a CVD of +$247,791, confirming sustained net buying. Spot volume reached $2,419,633 across 25,872 trades, with net buying occurring in 14 of the last 24 hours.
The latest daily buy ratio of 53.8% sits at the 79th percentile of the last 322 days, against a median of 50.8% - stronger buying than most days.
Was that an ordinary day?
The same Binance spot measurements for STX, averaged over the days leading up to the story.
Over the preceding week, STX saw a 7-day average buy ratio of 52.1%, with the latest day showing a 3.2 point increase above that average. The coin experienced a 20.6% price change over eight days, driven by a total volume delta of +$941,667. However, current 24-hour spot volume of $2,419,633 is only 0.58 times the weekly average, suggesting lower relative activity today. Net buying was recorded on 6 of the past 7 days, indicating a generally bullish trend. This recent daily performance is slightly above the weekly norm, but total volume remains subdued compared to historical averages.
