In Ruby, we can use the strip method to remove both leading and trailing whitespaces from a string. Here's how:
Example 1:
str = " hello world "
new_str = str.strip
puts new_str
Output:
"hello world"
Example 2:
str = " I love Ruby programming! "
new_str = str.strip
puts new_str
Output:
"I love Ruby programming!"
As you can see, the strip method removes all leading and trailing whitespaces from the string, leaving only the desired characters.
