BCA PART A 6. Implement a sequential search

 

def sequential_search(arr, target):

    """

    Perform a sequential search to find the target in the given list.

   

    Parameters:

        arr (list): The list to search in.

        target: The element to search for.

       

    Returns:

        int: The index of the target if found, otherwise returns -1.

    """

    for i in range(len(arr)):

        if arr[i] == target:

            return i

    return -1

# Accepting input from the user

arr = input("Enter elements of the list separated by space: ").split()

arr = [int(x) for x in arr]  # converting input strings to integers

target = int(input("Enter the element to search for: "))

# Performing sequential search

result = sequential_search(arr, target)

# Displaying the result

if result != -1:

    print(f"Target {target} found at index {result}.")

else:

    print(f"Target {target} not found in the list.")

Output :

Enter elements of the list separated by space: 1 3 45 6 8 90 Enter the element to search for: 3 Target 3 found at index 1.

Output 2:

Enter elements of the list separated by space: 3 5 7 89 -1 0 34 Enter the element to search for: 8 Target 8 not found in the list.
