Table of content Binary Search Algorithm Implementation Previous Quiz Next 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 ...
Given two sorted arrays A, B, give a linear time algorithm that finds two entries i,j such that|A[i]−B[j]|is minimized. Prove the correctness of your algorithm and analyze the running time. Solution:我们可以对于每个a[i],然后再B数组中二分查找距离a[i] “最近”的数,这里的“最近...

This is how I usually approach the binary search implementation. First, I define aninvariantfor the pointers. For example, in some cases, I want to ensure that the left pointer (l) always points to a position that is strictly less than the answer, while the right pointer (r) should alwa...
The explanation above provides a rough description of the algorithm. For the implementation details, we'd need to be more precise. We will maintain a pair$L < R$such that$A_L \leq k < A_R$. Meaning that the active search interval is$[L, R)$. We use half-interval here instead of...
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.
