利用上题中的寻找target左边界的思路,很容易通过修改if判断来找出target右边界。 (题目来源于LintCode,具体解法详见[LintCode] Search For A Range) classSolution {public:/** @param A: an integer sorted array * @param target: an integer to be inserted * @return: a list of length 2, [index1, ...
pivot. This is possible only because the array is sorted. Since the array is sorted it's guaranteed that search key will not appear in the left half as it's greater than the pivot. So we can discard the left half and shrink our range to [pivot index+1, right] for further search. ...

Supposed you have 2D array with integers sorted both horizontally and vertically.How do you apply Binary Search on 2D array? If you find any occurrence of the value you are looking for return true else false. What is the complexity? For example the 2D array could look like the following: ...
Binary search is a fast search algorithm with run-time complexity of (log n). This search algorithm works on the principle of divide and conquer, since it divides the array into half before searching. For this algorithm to work properly, the data collection should be in the sorted form. ...
In this lesson we learn how to implement a Binary Search Algorithm usingTypeScript / Javascript, and we describe the problem that it solves. function binarySearch( array: number[], element: number, start: number=0, end: number= array.length -1): number {if(end <start) {return-1; ...
