pub fn change_places(
matrix: &[Vec<i64>],
target: usize,
source: usize,
) -> Result<Vec<ChangePlace>>Expand description
The cheapest edit from the target to the source read out of a matrix
already filled, each change with the places of the two hashes it is
between: the by-position twin of calculateChangesList.
ยงErrors
Either side with nothing hashed, or a matrix nothing can be traced through.
