def binary_search_recur(arr, low, high, x): if low > high: return -1 mid = (low + high) // 2 if x < arr[mid]: return binary_search_recur(arr, low, mid - 1, x) elif x > arr[mid]: return binary_search_recur(arr, mid + 1, high, x) else: return mid 1 2 3 4 ...
这个比较简单,因为循环确定target>=arr[l]&&target < arr[r],那么第一个比target大的数肯定就是arr[r]。 Worst case performance: O(log n) Best case performance: O(1) Average case performance: O(log n) Worst case space complexity: O(1) 今天算是把怎么验证程序的正确性研究了一天了。。。201409...
Binary Search Algorithm: In this tutorial, we will learn about the binary search algorithm, and it's time complexity in detail and then, implemented it in both C & C++. As a follow up there are several use cases or variations of binary search. By Radib Kar Last updated : August 14,...
Binary search algorithm is a fast search algorithm which divides the given data set into half over and over again to search the required number.
Binary Search: Algorithm, Code, and CachingJon BentleyInformationweek
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. For this algorithm to work properly, the data collection should be in a sorted form.C C++ Java Python Open Compiler #include<stdio.h> void ...
