hi gives an upper bound on the array index to search. If not specified defaults to array.length-1 The range [lo,hi] is inclusive (closed) bounds.le and bounds.lt will return lo - 1 if no element is found that ==y bounds.ge and bounds.gt will return hi + 1 if no element is...

When binary search is used to perform operations on a sorted set, the number of iterations can always be reduced on the basis of the value that is being searched. Let us consider the following array: By using linear search, the position of element 8 will be determined in the9thiteration....

Majority Element(ARRAY-BINARY SEARCH) QUESTION Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times. You may assume that the array is non-empty and the majority element always exist in the array....
2二叉排序树(binary search tree) 之前我们遇到的 vector list queue 这都是线性结构。 也就是从头到尾,逻辑上一个挨着一个的结构。 这种结构最大的缺点就是元素数量变的很多之后,就像一个很长的绳子,或者钢筋,中间插入元素和删除元素都非常的费劲。
