This simplified the Kata for me thank you.

Why don't you recommend using it in this case? Thank You.

The description says " some possible expressions", it does not mean to list all possible expressions. Finding out all possibilities is a task for users.

With the numbers 1, 2, and 3, here are some possible expressions:

Here you need to add the case of (a + b + c) -_-

thank you it worked for me!

I fixed the bug in the C version, your code would pass the tests now :)

somebody raised it there with more details

Formally yes: any sequence of steps to solve a problem is an algorithm. But in practice, an "algorithmic problem" usually means a problem where the focus is on finding a more efficient method than trivial brute force or a simple loop. Otherwise, the term would lose its meaning

"algorithm" literally means "a method to solve something". Going through all possible combination is a valid way to solve this problem, so it is a valid algorithm :)

Don't try to find an algorithm for this task, even though it's labeled "algorithms." This assignment is one of the most confusing. I recently started programming, and seeing the label, I thought I needed to use an algorithm. In reality, algorithms here would only slow down the code, and in the end, you'll still have to go through all combinations.
