如果待查找序列 seq 中有多个元素与 key 相等,那么,binary_search 函数只是返回其中一个元素的索引。比如,序列 seq 为 [1,2,5,5,5,5,7,8,9], key 的值为 5。 中间元素 seq[4] == 5,所以结果为 4。如果要返回从左到右第一个与 key 相等的元素的索引(此索引为 2),该如何做呢? 我们回想一下 ...

The binary search begins by comparing the searched element with the middle element of the array. Since ‘mid’ calculate for every iteration or recursion, we divide the array into half and then try to solve the problem. If the searched value is less than the element in the middle of the ...

Both the left and right subtrees must also be binary search trees. A single node tree is a BST Example An example: 2 / \ 1 4 / \ 3 5 The above binary tree is serialized as{2,1,4,#,#,3,5}(in level order). Note 第一种,先跑左子树的DFS:如果不满足,返回false. ...
