Introduction

C# is a versatile programming language widely used for developing various types of applications. Having a strong understanding of some popular and useful algorithms can significantly improve your problem-solving skills and programming efficiency. In this article, we’ll go through the top 10 most popular and useful algorithms in C#, complete with code samples.

Algorithm 1: Binary Search

Binary Search is a widely used searching algorithm that works on sorted arrays or lists. It is efficient and fast, with a time complexity of O(log n). Binary search is useful when you need to quickly find an element in a sorted list or array, as it takes fewer steps compared to linear search, which has a time complexity of O(n).

Here’s the code:

public static int BinarySearch(int[] arr, int target) {
    int left = 0;
    int right = arr.Length - 1;

    // Continue searching until the left index is less than or equal to the right index
    while (left <= right) {
        int mid = left + (right - left) / 2;

        // If the middle element is the target, return its index
        if (arr[mid] == target) {
            return mid;
        }

        // If the middle element is less than the target, move the left index to mid + 1
        if (arr[mid]…
