warning: unused variable: `n`

help: `n` is captured in macro and introduced a unused variable

= note: `#[warn(unused_variables)]` on by default
= note: this warning originates in the macro `input_internal` which comes from the expansion of the macro `inputv` (in Nightly builds, run with -Z macro-backtrace for more info)
warning: value assigned to `ans` is never read
--> src/main.rs:22:13

= help: maybe it is overwritten before being read?
