Write the output that is printed when the given method below is passed each of the following dictionaries and lists as its parameters.
Recall that dictionaries print in a {{key1, value1}, {key2, value2}, ..., {keyN, valueN}} format.
Though dictionaries usually have unpredictable ordering, for this problem, you should assume that when looping over the dictionary or printing a dictionary, it visits the keys in the order that they were added to the dictionary in the order they are declared below.
If a dictionary adds a key that already exists, it retains its current position in the ordering.
public static void CollectionMystery5(List<string> list1, List<string> list2)
{
Dictionary<string, string> result = new Dictionary<string, string>();
for (int i = 0; i < list1.Count; i++)
{
string s1 = list1[i];
string s2 = list2[i];
if (!result.ContainsKey(s1))
{
result[s1] = s2;
}
else if (!result.ContainsKey(s2))
{
result[s2] = s1;
}
else
{
result[s1 + s2] = s1;
}
}
Console.WriteLine(result);
}
