How to pop the first element of a vector in Rust

Answer 1

fn main() {
    // Initialize a vector equivalent to std::vector in C++
    let mut vec = vec![1, 2, 3, 4, 5];

    // Check if the vector is not empty
    if !vec.is_empty() {
        // Remove the first element
        vec.remove(0);
    }

    // Print the updated vector
    for num in &vec {
        print!("{} ", num);
    }
    println!();
}
