136. Single Number Introduction Given a non-empty integer array nums, where every element appears twice except for one, find that single element. You must design and implement an algorithm with linear time complexity that uses only constant extra space. Example 1: Input: nums = [2,2,1] Output: 1 Example 2: Input: nums = [4,1,2,1,2] Output: 4 … Read more
Although the concept of antibody-drug conjugates (ADCs) seems straightforward, developing successful and effective drugs involves numerous challenges. For a successful ADC product, scientists must optimize various parameters, including ADC stability (for instance, the drug payload should not be released before the ADC reaches its target in the body), pharmacokinetics (e.g., the payload should not accumulate … Read more
Analog Signal refers to information represented by continuously varying physical quantities, such as temperature, humidity, current, voltage, etc. Its value changes continuously and can take an infinite number of different values within a certain time range. Digital Signal has discrete, non-continuous values and is commonly represented by 1 and 0 in binary. In digital circuits, … Read more
Developing a File Encryption and Decryption Tool in C Language In the modern information age, data security is particularly important. Today, we will learn how to develop a simple file encryption and decryption tool using the C language. This tool implements basic encryption and decryption functions through the XOR algorithm. 1. XOR Encryption Principle XOR … Read more

Photographer: Product Manager This Skewered Food Shop Has Finally Opened When reading various encryption articles, you often see that the authors use numbers as examples for encryption. However, in real life, we communicate in Chinese. So how can we encrypt Chinese text? In the article “Don’t Worry, No One Can Snooze Our Chat Messages”, we … Read more
In a new study, researchers from the Max Planck Institute for Intelligent Systems in Germany combined robotics with biology, equipping Escherichia coli with artificial components to construct biohybrid microrobots. First, they attached several nanoliposomes to each E. coli, which encapsulated indocyanine green (ICG) that melts when exposed to near-infrared light. Moving inward, these nanoliposomes contain … Read more
