The method described in the theory performs binary search for arrays sorted in ascending order. Your task here is to modify the method such that: it allows searching in descending sorted arrays; it returns the first index of a target element from the beginning of the array (the leftmost index...
二分查找(Binary Search)Java实现 使用二分查找的序列必须是有序的。 时间复杂度O(logn),每次当前序列长度的一半。 1. 递归实现 /*** To search if the target is in a given array. If find, return the position of * the target in a given array. If not, return -1.*/publicintbsRecursion(int...
// 查找节点的方法booleansearch(intkey){returnsearchRec(root,key);// 从根节点开始递归查找}// 递归查找的辅助函数booleansearchRec(Noderoot,intkey){// 基本情况:如果当前节点为空,返回falseif(root==null){returnfalse;}// 如果找到了关键字,返回trueif(key==root.key){returntrue;}// 根据BST特性继续...
我理解的数据结构(五)—— 二分搜索树(Binary Search Tree) 一、二叉树 和链表一样,动态数据结构 具有唯一根节点 每个节点最多有两个子节点 每个节点最多有一个父节点 具有天然的递归结构 每个节点的左子树也是二叉树 每个节点的右子树也是二叉树 一个节点或者空也是二叉树 ...

index= binSearch(Arrays.copyOfRange(arr, 0, middle), element); }returnindex; } 要保证接口为binSearch(array, target),所以此处使用了Arrays.copyOfRange()--导致造成了额外的空间消耗(创建新的数组)。 Version 2: //注意这种切换接口的方式publicstatic<TextendsComparable<?superT>>intbinSearch_JDK(T[...
