// Rust program to demonstrate 
// the match statement

fn main() {
    let mut weekNum:i32 = 2;

    let day = match weekNum {
    1=> "Sunday",
    2=> "Monday",
    3=> "Tuesday",
    4=> "Wednesday",
    5=> "Thursday",
    6=> "Friday",

    _=> "Invalid week number"
    };
    
    println!("Week day is: {}",day);

Explanation:

Here, we created an integer variable weekNum with an initial value of 2. Then we found the weekday from week number using the match statement and printed the result.
