I came up with almost the same idea as the editorial . ↵
The only difference is that I queried $i$ and $i+1,i+2,...,n$ to find a magnet (I think it will be either the first or the second of them),instead of $i$ and $1,2,3,...,i-1$.And then I used the same approach just as the editorial says.↵
↵
However,I got TLE on test 6. qwq↵
↵
Today,I did a binary search on test 6.I get the test case that made me TLE, but it passed when I tested it locally.↵
↵
I do wonder why it goes wrong.↵
