# The foreach Loop Solutions

#### The `foreach` Loop Dersi Problem Çözümleri

To have an associative array that works the opposite of `names`, the types of the key and the value must be swapped. The new associative array must be defined as of type `int[string]`.

Iterating over the keys and the values of the original associative array while using keys as values and values as keys would populate the `values` table:

    import std.stdio;

    void main() {
        string[int] names = [ 1:"one", 7:"seven", 20:"twenty" ];

        int[string] values;

        foreach (key, value; names) {
            values[value] = key;
        }

        writeln(values["twenty"]);
    }
