欧拉前差公式通用程序 欧拉前差公式的算法，精度不是很高，误差相对比较大- In front of Euler in front of difference formula general routine Euler the difference formula algorithm, the precision is not very high, the error relative quite is big

找不到分类，内容是欧拉差分算法解方程。比较简单适合初学者。-not classified, as is the difference Algorithm for Euler equations. Relatively simple for beginners.

图论算法实现，含树，欧拉圈，霍夫曼编码，图的连通性，着色树，最短路径等，且采用加载皮肤界面，界面美观-Graph algorithms, including trees, Euler circles, Huffman coding, graph connectivity, coloring trees, shortest paths, and the interface with loads of skin, beautiful interface
