Let's say we have such an array: myArray = [A, A, B, B, C, C, D, E]I would like to create an algorithm so that it will find all the combinations that add up to the whole array, where none of the elements are repeated.

## How to find all partitions of a multiset, where each part has distinct elements?

Let's say we have such an array: myArray = [A, A, B, B, C, C, D, E]I would like to create an algorithm so that it will find all the combinations that add up to the whole array, where none of the elements are repeated.

## Finding three integers such that their sum of cosine values become max

There are three integers x, y and z (each of them >= 1) and a given upper bound integer n < 10^6. Also, n = x + y + z and output = cos(x) + cos(y) + cos(z).

## Find all combinations of a set of numbers that add up to a certain total

I've seen a few solutions to similar problems, but they all require iteration over the number of items to be added together.

## R – find all combinations of a set of numbers that add up to a certain total

## Create all combinations of letter substitution in string

I have a string "ECET" and I would like to create all the possible strings where I substitute one or more letters (all but the first) with "X".

## How to calculate the product from combinations of several vectors in R?

I feel it hard to give an accurate title, though I have tried my best. Here's my problem.I would like to get a vector e, such that e consists of the product calculated from the combinations of values chosen from a, b, c and d.

## Picking unordered combinations from pools with overlap

I have pools of values and I would like to generate every possible unordered combination by picking from certain pools.
