str1
with a value of "Hello World"
.str1 = 'Hello World'
modified_str = str1[0..-4]
puts 'Modified string is: ' + modified_str
Modified string is: Hello Wo
In this example,
str2
with a value of "apple"
.str2 = 'apple'
modified_str = str2[0..-3]
puts 'Modified string is: ' + modified_str
Modified string is: app
