combinationsReplacement(x, k): any[][]

Defined in: src/combinations_replacement.js:13

Implementation of Combinations with replacement Combinations are unique subsets of a collection - in this case, k x from a collection at a time. ‘With replacement’ means that a given element can be chosen multiple times. Unlike permutation, order doesn’t matter for combinations.

Parameters

x

any[]

any type of data

k

int

the number of objects in each group (with replacement)

Returns

any[][]

array of combinations

Example

combinationsReplacement([1, 2], 2); // => [[1, 1], [1, 2], [2, 2]]
