This is basically a slightly disguised version of inverse triangular number + triangular row sum. There are already duplicates on each part of the task.

raulbc777 had already made many such katas, so please unpublish before it gets retired plus the issues below.

there is no point in asking for 4 data in the output as long as one of them is the complete line.

• if you want all the numbers in the line, there is no point in asking for the second and fourth data (redundancy)
• if you actually go for performances, just remove the third ouput. This will consume a f...ing lot of time for nothing => go with the 3 others

cheers

I suggest you put this kata back to draft and read how to author kata. You are missing random tests.

Function name in JS should be camelCase.

No Random Tests.

No Sample Tests.
