binary search: Required elements must be ordered, and if they are unordered, sort operations first 　　The basic idea : also known as binary lookup, belongs to the ordered search algorithm. With the given value K first compared with the middle node of the keyword, the middle node divides the Line table into two sub-tables, if the equality is found successful; if not equal, then according to the comparison between K and the middle node keyword to determine which child table next, so recursively, u
