The push() function is used to push a character to the end of the string. It will append that character at the end of the string. Syntax string1.push('x'); JavaScript Copy Example fn main() { let str1=String::from("String text"); str1.push('x'); println!("This is string: ...

When the empty string is used as a separator, it separates every character in the string, along with the beginning and end of the string. let f: Vec<_> = "rust".split("").collect(); assert_eq!(f, &["", "r", "u", "s", "t", ""]);Run Contiguous separators can lead to...
