Why does this c# code has two angular bracket '>>' after IHeapifyable in this line-CodePudding

The method is in a class Heap which creates a Heap data structure in C# This method finds the Kth minimum value in O(K log n) time What does this line exactly do

List<IHeapifyable<K, D>> temp = new List<IHeapifyable<K, D>>();

Can someone explain this specific line in a C# code The whole code is over here

public IHeapifyable<K, D> KthMinElement(int k)
    {
        if (Count is 0) throw new InvalidOperationException();
        if (k <= 0 || k > Count) throw new ArgumentOutOfRangeException();

        IHeapifyable<K, D> kthMin = null;
        List<IHeapifyable<K, D>> temp = new List<IHeapifyable<K, D>>();
        for (int i = 1; i <= k; i  )
        {
            if (i == k) kthMin = data[1];
            temp.Add(this.Delete());
        }
        foreach (var node in temp) this.Insert(node.Key, node.Data);

        return kthMin;
    }

CodePudding user response：

The angle brackets are enclosing the generic type parameters. It's using a List<T> where T is IHeapifyable<K, D>, so it's a List<IHeapifyable<K, D>>. It's just like if you were to nest method calls like this:

Method1(Method2(arg));

so you end up with two closing parentheses at the end.

CodePudding user response：

The angle brackets are the opening and closing of what is contained in the data type they are describing.

List<IHeapifyable<K, D>> temp = new List<IHeapifyable<K, D>>();

So what this line says is: Create a List data type containing one or more IHeapifyable<K,D> data types and assign it to the variable temp
