The program illustrates searching a number in a given list using Binary search. Input and Output: #include <iostream.h> const int n=5; void main() { int i,s,m,low=0,mid,top,p; int a[n]; cout<<"Enter the number of elements"; cin>>m; cout<<"Enter the elements in sorted orde...
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,...
