In Rust, you can sort characters in a string by converting the string to a mutable character array, sorting the array, and then converting it back into a string.
In this example,
str
.fn main() {
let mut str = String::from("hello world");
let mut chars: Vec<char> = str.chars().collect();
chars.sort();
str.clear();
for c in chars {
str.push(c);
}
println!("Sorted string in ascending order: {}", str);
}
Sorted string in ascending order: dehllloorw
In this example,
str
.fn main() {
let mut str = String::from("hello world");
let mut chars: Vec<char> = str.chars().collect();
chars.sort_by(|a, b| b.cmp(a));
str.clear();
for c in chars {
str.push(c);
}
println!("Sorted string in descending order: {}", str);
}
Sorted string in descending order: wroolllhed
