How to convert a vector of ints to a vector of strings in Rust

Answer 1

fn convert_to_string_vector(numbers: Vec<i32>) -> Vec<String> {
    // Map each integer to its string representation and collect into a Vec<String>
    numbers.into_iter().map(|num| num.to_string()).collect()
}

fn main() {
    let numbers = vec![1, 2, 3, 4, 5];

    // Convert the vector of integers to a string vector
    let string_array = convert_to_string_vector(numbers);

    println!("String vector:");
    for str in string_array {
        println!("{}", str);
    }
}
