LeetCode Animation
Demonstrate all the questions on LeetCode in the form of animation
...The goal of the project is to help learners understand complex algorithmic concepts intuitively by showing step-by-step animated explanations instead of relying solely on static code or text. Each animation corresponds to a specific problem and illustrates how data structures and algorithms operate dynamically, making it easier to grasp their underlying logic. The project also includes a curated set of 40 problems from the “Sword Pointing to Offer” series—commonly asked in technical interviews—accompanied by detailed analyses and visual breakdowns. These materials are designed for both beginners starting their algorithm journey and experienced developers seeking to reinforce their understanding. ... -

Last Java Collection Library
Java library to work with scalar arrays as usual Collections
The package allows to work with scalar arrays as usual collections. The problem with a scalar array Java templates don't support scalar types as generic parameters. Java code working with collection interfaces such as List or Collection is inapplicable for arrays. Some libraries supply methods to work with object array. These methods are generic and built-in types int, boolean, long, short, byte, double, float suffer. -
