- Understanding Bubble Sort Algorithm (with Examples in Java)
- Detailed explanation of Bubble Sort: a simple sorting algorithm Bubble sort is one of the simplest sorting algorithms. It works by repeatedly comparing adjacent elements and swapping them if they are out of order. For example, if the sort order is ascending, adjacent elements are compared and the larger element is placed on the right. In each iteration, we compare only the unsorted elements and place the largest element at the last position of the unsorted elements in the array. The algorithm is aptly named bubble sort because the elements move toward the right side of the array on each iteration, like a bubble rising to the surface of the water. How bubble sort works Suppose we want to sort this array in ascending order: first iteration In the first iteration, we try to move the largest element to

- Understanding Quick Sort Algorithm (with Examples in Java)
- Detailed explanation of QuickSort algorithm: an efficient sorting tool QuickSort is an efficient sorting algorithm based on the divide-and-conquer strategy. The divide-and-conquer method decomposes the problem into smaller sub-problems, solves these sub-problems separately, and then combines the solutions of the sub-problems to obtain the final solution. In quick sort, an array is divided by selecting a partition element, which determines the split point of the array. Before partitioning, the position of the partitioning element is rearranged so that it is before the element that is larger than it and after the element that is smaller than it. The left and right subarrays will be divided recursively in this manner until each subarray contains only one element, at which point the array is sorted. How quick sort works Let's take the example of sorting the following array in ascending order: Step 1: Select the pivot element

- Enhancing Security with App Signature Verification
- Enhance application signature verification to improve security In the ever-changing world of mobile app development, security is no longer a luxury but a necessity. A key aspect of application security is application signature verification. This process ensures the integrity and authenticity of the application, preventing tampering and unauthorized modification. Let’s explore what application signature verification is, why it’s important, and how to implement it effectively. What is app signature verification? App signature verification involves verifying an application's digital signature to ensure it has not been altered since it was signed by the original developer. Every Android app has a unique cryptographic signature generated using a keystore. When you install or update an app, Android compares its signature to existing signatures. If you sign

- Leetcode — Permutation Difference between Two Strings
- This is a simple question with the following meaning: Given two strings s and t, where each character in s occurs at most once and t is a permutation of s. The permutation difference between s and t is defined as the sum of the absolute differences between the index of occurrence of each character in s and the index of its occurrence in t . Returns the permutation difference between s and t. Example 1: Input: s = "abc", t = "bac" Output: 2 explain: For s = "abc" and t = "bac", the difference in the permutations of s and t is equal to the sum of: "a" in s

- How does Java work under the hood?
- First, what is Java? Java is a multi-platform object-oriented programming language. "Multi-platform" means that not only can it be used to create web applications, mobile applications, and games, but it can also run on any device you can think of. Object-oriented programming (OOP) means that its main concepts revolve around objects, which are simply data with properties and behaviors. Now, how does it work in our computers? The Java process can be likened to a journey, and the best way to describe it is to break it down into steps: Step 1: Code Script As we all know, code needs to be written in the form of ".java" files in an editor (Notepad, IDE, etc.). But this code can only be understood by humans, so

- Trampoline, example in Java
- Let's write a simple program that adds numbers from n to 0. But instead of using iterative approach, why not try recursive approach? We call this program sum. We know sum(0) == 0, so this is our base case. How do we arrive at the base case? sum(n) == n sum(n-1) until finally sum(0) is reached. The Java code is as follows: int sum(int n) { if (n == 0) { return 0; } return n sum(n - 1); } Recursion problem? Recursion on base case distance input
