comp_input

Input library for competitive programming.

Example: weighted graph as edge list

#[macro_use]
extern crate comp_input;

fn main() {
    input! {
        n, m: usize,
        edges: [(usize1, usize1, u64); m],
    }
}

The variables n, m and edges then exist as local variables in scope.

Fragment	Description
`u8, u16, u32, u64, usize`	Unsigned integer (base 10)
`i8, i16, i32, i64, isize`	Signed integer (base 10, optional +/- prefix)
`usize1`	Like `usize`, but subtract 1 from the result (useful for 1-based input formats)
`char`	A single character
`String`	A sequence of non-ASCII-whitespace characters
`(T1, T2), (T1, T2, T3), ...`	Heterogeneous tuple of other input fragments, read in order
`[<T>; <n: expr>]`	`n` items parsed against `T`, returned as `Vec`
`[<T>; const <n>]`	`n` items parsed against `T`, in an array. `n` must be compile-time constant
