closest-sum-pair 0.4.0

closest_sum_pair

Fast. Clever. Free of Recursion. No while bound loops, so least runtime strikes.

As it expects unsorted list, The time complexity is O(NlogN). Space complexity O(1).

Quick Start

use closest_sum_pair::interface::find_pair;

fn main() {
    let mut list = [-2, -4, -7, -2, -5, -13, -7];

    let desired_sum = -1;

    let pair = find_pair(&mut list, desired_sum);

    println!("pair {:?}", pair) // (-2, -2)
}

version note: Made the api easier to use.
