Hey all, kind of feeling my way around the forums and I got a question… is there a central place to see the solutions other people came up with, like on Leetcode?

I find it useful after I solve a challenge, or when I get stuck, to see other people’s approaches.

If you have a solution to post for discussion, where is the best place?

For example, in the Javascript Pairwise challenge, I’ve found several solution posts, but they are a locked.

In my solution, for example, I used a Set, and it would be nice to be able to talk to people about the prose and cons of different approaches.

```
function pairwise(arr, arg) {
const set = new Set();
let sum = 0;
for(let i = 0; i < arr.length; i++) {
for(let j = i+1; j < arr.length; j++) {
if(arg - arr[i] == arr[j]) {
if(!set.has(i) && !set.has(j)) {
set.add(i)
set.add(j)
sum += i + j
}
}
}
}
return sum;
}
pairwise([1,4,2,3,0,5], 7);
```

Thanks!
