cplit

Competitive Programming Library in Rust

This library aims to provide a set of algorithm, data structure and tools for competitive programming.

There are several philosophies behind this library:

• Simple: The library should be simple and fast to use, as time is precious in competitive programming.
  • Do not overuse Option, Result to provide unnecessary boundary checks (panic is fine).
• Extensible: Most of algorithms and data structures should not be limited to a specific type.
  • Design genetic traits to allow different types to be used (including potentially user-defined types like matrices).
• Efficient: The library should be efficient enough for competitive programming problems.
• Comprehensive: The library should be readable and understandable for educational purposes.
• Tested: The library should be tested with some problems from online judges to ensure its correctness.
• Indexed from 1: The library should use 1-based index for most of the algorithms and data structures while leaving the index 0 for buffer manipulation.
  • This is because most of the problem use 1-based index.
  • Index 0 should default be set to ZERO.

Examples

use cplit::scanln;

fn main() {
    let (a, b): (usize, usize);
    scanln!(a, b);
    println!("{}", a + b);
}
