rustHow to join array in Rust

Joining an array in Rust can be done using the join method. This method takes a string as an argument, which will be used as a separator between the elements of the array.

Code example:

let array = ["a", "b", "c"];
let joined_array = array.join(", ");
println!("{}", joined_array);

Output

a, b, c

Explanation of code parts:

1. let array = ["a", "b", "c"]; - This line creates an array of strings with the elements "a", "b", and "c".
2. let joined_array = array.join(", "); - This line calls the join method on the array, passing in a string with a comma and a space as an argument. This will be used as a separator between the elements of the array.
3. println!("{}", joined_array); - This line prints the joined array to the console.
