Tried to do it 3-4 times and always gave up. Finally got it...

I'm stuck on the same case in Rust, yet it has 1k solves.

vec![121, 144, 19, 161, 19, 144, 19, 11], vec![121, 14641, 20736, 36100, 25921, 361, 20736, 361]

assertion failed: `(left == right)`
left: `false`,
right: `true`

I assume the case was meant to have 19, 19, 190, not three 19s.

Could be just me and it's not a big issue but... I think there's an extra semicolon in the Rust sample tests. I removed it and reset the Kana but it's still there.
