Thesplit_whitespace()is used to split the input string into different strings. Since it returns the iterator, we can iterate it through the token. Example Code: fnmain(){letwords="Rust is a programming language".to_string();letmuti=1;fortokeninwords.split_whitespace(){println!("token {} {}",i,token);i+=1;}} Output: token 1 ...

grocery.split(':')- since there are no colons in the string,split()does not split the string. Example: split() with maxsplit We can use themaxsplitparameter to limit the number of splits that can be performed on a string. grocery ='Milk#Chicken#Bread#Butter'# maxsplit: 1print(grocer...
