使用递归的数组的最小值。这是如何运作的?

Minimum of an array using recursion. How does this work?

有人可以解释一下下面的代码是如何工作的吗?

int minElement(int arr[], int n) {
    if(n == 1)
        return arr[0];
    else {
        int m = minElement(arr, n-1);

        if(m < arr[n-1])
            return m;
        else
            return arr[n-1];
    }
}

我评论了每一行

int minElement(int arr[], int n) {
   if(n == 1)  //When you reach the beginning of the array
        return arr[0]; // Return the first element
    else {
        int m = minElement(arr, n-1); // See what the minimum spot is below n-1 index

        if(m < arr[n-1]) // If the min element is below you return the min element
            return m;
        else
            return arr[n-1]; // If not return your value as the min element up until the index
    } // Repeat till you reach the top again
}
