## 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.

## 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".
