Macro cp_tricks::input

macro_rules! input {
    (source = $s:expr, $($r:tt)*) => { ... };
    ($($r:tt)*) => { ... };
}

input macro for parsing input from all CP platforms

Examples

input! {
    source = s,
    t: usize,
    k: [(usize, usize); t] 
}

Omit source when submitting, while developing, you can save the input in file and use this

use std::fs::File;
use std::io::Read;
let mut sc = File::open("test.txt").unwrap();
let mut s= String::new();
sc.read_to_string(&mut s).unwrap();
