How to find the uncommon elements from two arrays in Rust

Answer 1

fn main() {
    let arr1 = vec![1, 2, 7, 5, 8, 16, 18];
    let arr2 = vec![1, 8, 5, 12, 19, 52, 103, 150];

    let uncommon_arr1: Vec<_> = arr1.iter().filter(|&&obj| !arr2.contains(&obj)).collect();
    let uncommon_arr2: Vec<_> = arr2.iter().filter(|&&obj| !arr1.contains(&obj)).collect();

    let uncommon: Vec<_> = [uncommon_arr1, uncommon_arr2].concat();

    println!("{:?}", uncommon);
}


   
/*
run:
  
2, 7, 16, 18, 12, 19, 52, 103, 150]
