How to Trim a String in Ruby ?

To trim a string in Ruby, you can use the strip, lstrip, and rstrip methods of the String class.

In this example,

We assign a string value of " Hello World " to the variable str1.
We then use the strip method on str1 to remove leading and trailing whitespace characters.
Finally, we print the trimmed string.

str1 = "   Hello World   "
trimmed_str1 = str1.strip
puts "Trimmed string is: '#{trimmed_str1}'"

Trimmed string is: 'Hello World'

In this example,

We assign a string value of " apple" to the variable str2.
We then use the lstrip method on str2 to remove leading whitespace characters.
Finally, we print the trimmed string.

str2 = "   apple"
trimmed_str2 = str2.lstrip
puts "Trimmed string is: '#{trimmed_str2}'"

Trimmed string is: 'apple'

In this example,

We assign a string value of "banana " to the variable str3.
We then use the rstrip method on str3 to remove trailing whitespace characters.
Finally, we print the trimmed string.

str3 = "banana   "
trimmed_str3 = str3.rstrip
puts "Trimmed string is: '#{trimmed_str3}'"

Trimmed string is: 'banana'
