Search algorithms are fundamental concepts in computer science. They are used to find a particular item in a collection of data. This guide will introduce you to some common search algorithms.
Common Search Algorithms
Here are some of the most common search algorithms:
- Linear Search: It checks each element in a list one by one until it finds the desired element.
- Binary Search: It works on a sorted list and divides the list in half with each iteration to find the desired element.
- Interpolation Search: An improvement over binary search for instances where the values in a list are numeric and uniformly distributed.
Example: Linear Search
Here's a simple example of how linear search works:
def linear_search(arr, x):
for i in range(len(arr)):
if arr[i] == x:
return i
return -1
arr = [1, 2, 3, 4, 5]
x = 4
result = linear_search(arr, x)
print("Element is found at index", result)
