题目：对记录序列：{55，13，23，72，109，67，2，78,13}分别使用顺序查找和折半查找算法实现特定关键字值记录的查找。然后建立该记录序列的二叉排序树，并在其上实现特定关键字值结点的查找和删除。-Title: on the record sequence: (), respectively 55,13,23,72,109,67,2,78,13 order to find and use half the search algorithm to achieve a specific keyword to find the value of the record. Then the establishment of the record sequence of binary sort tree, and in its values to achieve a specific keyword node to find and delete.
