I was working on a Question which was , Input - A list of numbers - [1,2,3,4,5] example We have to produce the subsets of this list and display those subsets whose sum is equal to 10 Output Format - [ [1,2] , [2,3] , [4,5,6] ] example Means we have to append those subset in a list whose sum is 1…

variable are immutable, you would need to use something like Enum.reduce . def display(list) do list |> Combination.combine() |> Enum.reduce([], fn val, acc -> if Enum.sum(val) == 6 do [val | acc] else acc end end) end To display the list you could just pipe the resu…

Thanks a Lot Brother , i was stuct in this for last 3days

[image] Gupta: def display(lis) do a=[] for vale <- Combination.combine(lis) do if Enum.sum(vale)==6 do # a IS UNUSED a=a++[vale] end end # THIS IS EQUAL TO a BEFORE for ... do ... end block IO.inspect(a) end This is a typical code, just not…

I am facing another problem with the output i.e this when ever my input is like - [1,2,3,4,5,6,7] , it gives me like this :- erts@eyrc:~/fr_task0_9999/.vscode$ elixir practice.exs [[4, 3, 2, 1], [7, 2, 1], [6, 3, 1], [5, 4, 1], [5, 3, 2], [7, 3], [6, 4]] erts@eyrc:~/fr_task0_9999/.vscode$ And …

Maybe it would be easier if you could explain what your combine/1 is supposed to be doing. As in what do you expect the outcome to be when calling that function with a list of integers. We might be able to better help if we understand the reason for the function and not just the output

basically my combine/1 is creating subset of the given list actually i have taken this code from internet and yes i think the output of my combine is affecting the output of my display/1 this is what i get from my combine/1 Combination.combine([1,2,3,4])|>IO.inspect() erts@eyrc:~/fr_task0_9999/…

Are you maybe looking for something like Enum.chunk_every/2 ? iex> Enum.chunk_every([1, 2, 3, 4, 5, 6], 2) [[1, 2], [3, 4], [5, 6]]

This is another question related to this https://forum.elixirforum.com/t/beginner-needs-help-with-sum-of-subsets/50511/78

I was just giving u the example of output format

The output is the same. It’s just IEx deciding to put the results on a new line. Probably because the result is too long to put on one line.

You’re saying display the subsets with a sum of 10, but the sums you’re outputting is 3, 5, 15?
