How-to-use

obviously like collections.Counter

A Counter is a Dictionary for couting objects. Keys are elements and Values are counts.

Counter Class

The Counter<T> class is a generic class that counts the occurrences of items in an enumerable or span of items. Initializes a new instance of the Counter<T> class with the specified enumerable of items.

var value = "abacaba";
var counter = new Counter<char>(value);

Dictionary<T, int> Get()

Gets the counts of items.

var counter = new Counter<string>(new[] { "apple", "banana", "apple", "orange", "banana", "banana" });
var counts = counter.Get();
// Output:
// { ["apple": 2], ["banana": 3], ["orange": 1] }

int Total()

Calculate the sum of the counts.

var counter = new Counter<string>(new[] { "apple", "banana", "apple", "orange", "banana", "banana" });
var total = counter.Total();
// Output:
// 6

IEnumerable Elements()

Returns an enumerable of elements based on the counts of items.

var counter = new Counter<string>(new[] { "apple", "banana", "apple", "orange", "banana", "banana" });
var elements = counter.Elements();
// Output:
// { "apple", "banana", "apple", "orange", "banana", "banana" }

IEnumerable<KeyValuePair<T, int>> MostCommon(int count)

Returns the specified number of most common elements along with their counts from the dictionary.

var counter = new Counter<string>(new[] { "apple", "banana", "apple", "orange", "banana", "banana" });
var elements = counter.MostCommon(2);
// Output:
// { ("banana": 3), ("apple": 2) }
