How to get vector subset in Rust

Answer 1

fn get_subset(v: &[i32], start_index: usize, length: usize) -> Vec<i32> {
    // Extract a subset of the array
    v.iter()
     .skip(start_index)
     .take(length)
     .cloned()
     .collect()
}

fn main() {
    let v = vec![3, 7, 9, 0, 4, 2, 1, 8];
    let start_index = 2; // Start index for the subset
    let length = 4;      // Number of elements in the subset

    let subset = get_subset(&v, start_index, length);

    println!("Subset: {:?}", subset);
}
