insertion sort algorithm

How would you implement the insertion sort algorithm?

  1. Sure, I’d be happy to help you with that! Here’s a sample implementation of the insertion sort algorithm in C#:

    “`
    public static void InsertionSort(int[] arr)
    {
    int n = arr.Length;
    for (int i = 1; i < n; i++)
    {
    int key = arr[i];
    int j = i – 1;
    while (j >= 0 && arr[j] > key)
    {
    arr[j + 1] = arr[j];
    j = j – 1;
    }
    arr[j + 1] = key;
    }
    }
    “`

    In this implementation, we start by iterating over the array and selecting a key element for each iteration. We then compare the key element to the elements that came before it in the array and shift them one position to the right if they are greater than the key element. This continues until we find the correct position for the key element. We repeat this process for each element in the array until the entire array is sorted.

    I hope this helps! Let me know if you have any other questions.
