How can I implement binary search in different programming languages?

You can implement binary search in languages like Python, Java, and C++. Which language would you like to start with?

Let's start with Python.

Here's a simple implementation of binary search in Python:

def binary_search(arr, target):
    left, right = 0, len(arr) - 1
    while left <= right:
        mid = (left + right) // 2
        if arr[mid] == target:
            return mid
        elif arr[mid] < target:
            left = mid + 1
        else:
            right = mid - 1
    return -1

Would you like to see it in another language?

Yes, can you show me the Java version?

Sure! Here's how you can implement binary search in Java:

public class BinarySearch {
    public static int binarySearch(int[] arr, int target) {
        int left = 0, right = arr.length - 1;
        while (left <= right) {
            int mid = left + (right - left) / 2;
            if (arr[mid] == target) {
                return mid;
            }
            if (arr[mid] < target) {
                left = mid + 1;
            } else {
                right = mid - 1;
            }
        }
        return -1;
    }
}
