Linear Search in Python
In this program, we will learn to search an element from the given array by using the linear search technique.
A linear or sequential search, as the name suggests, is done when you inspect each item in a list one by one from one end to the other to find a match for what you are searching for.
As compared with other techniques it is the worst searching algorithm with worst-case time complexity O (n).
- Input the number to be searched from the user and store in variable n.
- Array a is initialized.
- Using for loop, perform the linear search.
- Check if n==a[i], if true print “Number found”.
- Also, return its index or position.
- Iterate till we found the desired number which is asked by the user.
n=int(input("Enter the number to be searched (1-10):")) a=[1, 2, 4, 3,5,7,9,8,6,10 ] for i in range(1,(len(a))): if n==a[i]: print("number found at",i+1)
Enter the number to be searched (1-10):7 Number found at 6
