This article mainly implements following algorithms : two forks tree's graph processing algorithm, unordered list sequence search improved algorithm, the non-recursion established two forks tree and so on, and carries on the analysis to its algorithm. 本文主要实现了二叉树的图形处理算法、无序表顺序查找改进算法及非递归建立二叉树算法等,并对算法进行了分析。
