return binarySearchRecursive(arr, target, left, mid - 1); } } 复制代码 在这段代码中,binarySearchRecursive方法是一个重载方法,它接受一个数组arr和目标元素target作为参数,并调用了另一个私有方法binarySearchRecursive来执行实际的搜索。在私有方法中,我们使用递归的方式来执行二分搜索,直到找到目标元素或者left >...

Both the left and right subtrees must also be binary search trees. 查看题目中BST的定义,非常顺畅地想到用divide and conquer来做。假设我们已经用recursive calls来验证了左右子树(假如非空)是否为BST,如果有一结果为False,则无工作需要做,返回False即可,否则只需验证root的值是否大于左子树全部值并小于右子树...
