The core functionality of NumPy (Numerical Python) is specifically designed to handle multidimensional arrays, but its capabilities extend far beyond that. As the foundational library for scientific computing in Python, it centers around N-dimensional arrays (ndarray), deriving a full range of functionalities covering mathematical operations, linear algebra, data preprocessing, and more. 1. ndarray: NumPy’s Exclusive … Read more
Concept of union In Chinese, union is referred to as a union, joint, or collective. Its definition format is the same as that of a struct, but its meaning is entirely different. Below is the definition format of a union: union union_name { member_list } union_variable_name; Since its definition format is the same as that … Read more
It was a memorable Friday evening when I attempted to process five million GPS records of taxis in New York City using GeoPandas, and my 16GB RAM MacBook Pro began to roar like a helicopter taking off. This wasn’t my first time encountering issues during geospatial analysis, but watching the Jupyter kernel crash repeatedly made … Read more
【Problem】Given 4 billion unique unsigned int integers that are not sorted. Given a number, how can we quickly determine if this number exists among those 4 billion numbers? 1 billion is 9 zeros, so 4 billion is 4000000000. Our instinctive thought for a solution is to use a for loop to find the equal number, … Read more
Optimizing Program Size in Embedded C/C++ Development: Structure Optimization In <span>C</span> and <span>C++</span> programming, the memory layout of structures (<span>struct</span>) has a significant impact on program performance and memory usage, especially in embedded development where <span>RAM</span> is limited to <span>16K</span>, <span>8K</span>, or even <span>4K</span>; every byte counts, and there is no room for waste. This … Read more
