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.
List of input fragments
| 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 |
TODO
- Allow arbitrary parse functions
- Branching
- Loops (e.g. parse until -1)
