```

My output is `[1,37,99]`

But the expected answer is `[1,5,37,99]`

Both solution have the same cost because `arr[5] == 0`

, and `[1,37,99]`

is lexicographic smaller than `[1,5,37,99]`

.

Can someone explain why the expected answer is `[1,5,37,99]`

? Thanks!

`lexicographically smaller`

.
```
Path Pa1, Pa2, ..., Pan is lexicographically smaller than Pb1, Pb2, ..., Pbm, if and only if at the first i where Pai and Pbi differ, Pai < Pbi; when no such i exists, then n < m.
