Program Code – Mastering the Algorithm of Binary Search for Efficient Searching

def binary_search(arr, target):
    '''
    Perform a binary search on a sorted array.

    Parameters:
    arr (list): A sorted list of integers.
    target (int): The integer to search for in the array.

    Returns:
    int: The index of the target in the array if found, otherwise -1.
    '''
    low = 0
    high = len(arr) - 1

    while low <= high:
        # Calculate the middle of the current segment
        mid = (low + high) // 2

        # Check if the target is at the middle
        if arr[mid] == target:
            return mid  
        # If target is greater, ignore left half
        elif arr[mid] < target:
            low = mid + 1
        # If target is smaller, ignore right half
        else:
            high = mid - 1

    # Target was not found
    return -1

# Sample array
arr = [2, 3, 4, 10, 40]
target = 10

# Execute binary search
result = binary_search(arr, target)

if result != -1:
    print('Element is present at index', str(result))
else:
    print('Element is not present in array')

Code Output:

Element is present at index 3

Code Explanation:

This code snippet demonstrates the use of binary search, a classic algorithm for finding an item within a sorted list. The premise of binary search is quite simple: it repeatedly divides the search interval in half until the target value is found or the search interval is empty.

Here’s a breakdown of how it works:

1. Initialization: We begin by initializing two pointers, low at the beginning of the array and high at the end.
2. Loop Until Found or Exhausted: The while loop continues as long as low does not surpass high. This loop is the heart of the binary search.
3. Find the Middle: Inside the loop, we calculate the midpoint between low and high. This is where we check if the target value resides.
4. Check Middle for Target: If the item at the midpoint is the target, we’ve found our item and return its index.
5. Adjust Search Range: If the target is not at the midpoint, we adjust our search range. If the target is greater than the value at the midpoint, we eliminate the lower half of the range by setting low to mid + 1. Conversely, if the target is less, we cut off the upper half by setting high to mid - 1.
6. Target Not Found: If the loop exits without finding the target, indicating that low has surpassed high, we return -1 to signify the absence of the target in the array.

This approach drastically reduces the search time, making binary search a powerful tool for dealing with large, sorted datasets. It is a stark contrast to linear search, where items are checked one by one, without taking advantage of the array’s sorted nature. This efficiency is why binary search is a cornerstone algorithm in computer science, offering a logarithmic time complexity of O(log n), significantly faster than a linear search’s O(n) for large datasets.
