二叉搜索树(BST,binary search tree)
对于静态查找可以用二分查找,将查找时间复杂度降到 log2 n 。其中,虽然数据存储在线性的结构里,但我们事先对数据进行了处理,在查找的顺序过程中运用到判定树这样的结构,将线性上的查找过程转变为了在类似树上面的查找过程,其查找的效率就是树的高度。但如果查找的集合不仅有查找还有删除新增的需求,而树具有 ......

Exercise: Equivalent Binary Trees
这个Exercise的答案比较开放,不过遵循说明里面的基本要求: Walk遍历随机创建的有序2叉树,将值写入一个chan,按从小到大的顺序输出10个结果。需要注意的是,这个Exercise的随机2叉树说明里面明确了是tree.New(k)创建k, 2k, ..., 10k。所以输出的时候直接循环读1 ......

Educational Codeforces Round 152 (Rated for Div. 2) C. Binary String Copying
题目大意为给定一个01字符串,给定m个区间,对于每个区间进行一次局部排序,求能得到的字符串种类数 解法:因为字符串只包含0,1两个字符,我们观察可以得到,对于不同的区间来说如果排序后一样则说明肯定是某些位置在排序过程中无贡献,因此我们只需找出有贡献的位置即可 对于一个区间[l,r],来说,如果进行排 ......
