In the digital realm, where information is king, web applications frequently face the challenge of read-heavy traffic. This scenario is characterized by a significant majority of operations involving data retrieval rather than data modification or writing. Social media platforms, news aggregators, and e-commerce sites are prime examples, where the demand for fast and efficient data delivery is paramount. To keep up with such demands, developers and architects must employ strategic measures. Read-heavy traffic can strain the application’s resources, leading to slower response times and a degraded user experience. The key to managing this load is minimizing the time and resources required to serve each read request. Here are few strategies that can help achieve this. 1. Implementing Robust Caching Mechanisms Caching is the cornerstone of optimizing for read-heavy traffic. By storing a copy of frequently accessed data in memory, applications can serve future requests from this cache, dram

Caching is a pivotal strategy in software development, aimed at enhancing the speed and performance of applications. It involves temporarily storing copies of data so future requests for that data can be served faster. However, caches have limited memory, and deciding what to remove when the cache fills up is an essential aspect of cache management. This is where eviction policies come in. Understanding and implementing the right eviction policy can significantly impact the efficiency of the application. Eviction policies are algorithms that determine which items to remove from the cache to make room for new ones. The goal is to optimize cache usage by retaining the most useful data and discarding the least useful, based on specific criteria. Let's explore the most common eviction policies and their applications. 1. Least Recently Used (LRU) The LRU policy evicts items that haven't been accessed for the longest time. It operates under the assumption that data accessed recently

You are given an array representing the daily price of a stock. Your task is to write a Java algorithm to determine the best day to buy and the best day to sell the stock to maximize your profit. You are only permitted to complete a single transaction (i.e., buy one and sell one share of the stock), and you must sell the stock after you buy it. Input: An array of integers where each integer represents the stock price on a given day. For example, consider the following array of stock prices: int[] prices = {3, 5, 6, 1, 7, 2, 10, 9, 3}; Output: Your algorithm should return the best day to buy and the best day to sell to maximize profit. The days should be zero-indexed, where day 0 is the first day. If no profit can be made, return an appropriate message or values indicating such. Example: Given the input array [3, 5, 6, 1, 7, 2, 10, 9, 3] , your algorithm should return: Buy on day 3, sell on day 6 This is because buying the stock for 1 on day 3 and selling it for 10 on day 6 yields a m
