- As per name we understand that it means it will be searched in Linear order.
- Search the particular element one by one until not find.
- Linear Search not a more efficient searching algorithm.
- Time Complexity of the Linear Search is O(n), where n is the number of elements.
- For Example :
An array Store the some element
arr[5]= {1,5,4,2,6}
In this we have to search element 6.
So Linear search first check arr[0],
check second element arr[1] ... arr[4].After 4 comparison with element of array it will get element 6.
#include<iostream>
using namespace std;
int main()
{
int arr[5]={1,5,4,2,6};
int search = 6;
for(int i =0;i<5;i++)
{
if(arr[i]==search)
{
cout<<"Index of array " <<i;
}
}
return 0;
}
Index of array 4
