Get the most frequent items from a map from string to frequency.
This takes input such as that in ValueCountMatchSpy::Internal::values and returns a vector of the most frequent items in the input.
result | A vector which will be filled with the most frequent items, in descending order of frequency. Items with the same frequency will be sorted in ascending alphabetical order. |
items | The map from string to frequency, from which the most frequent items will be selected. |
maxitems | The maximum number of items to return. |
