remove a character from a string at a specific index in ruby

You can remove a character from a string at a specific index in Ruby using the slice! method. Here is an example:

main.rb
string = "hello world"
string.slice!(6)
puts string #=> "helloworld"
69 chars
4 lines

In this example, the character at index 6 (which is the space between "hello" and "world") is removed from the string using the slice! method.

Alternatively, you can use string slicing with range to remove a range of characters:

main.rb
string = "hello world"
string.slice!(5..6)
puts string #=> "helloworld"
72 chars
4 lines

In this example, the characters from index 5 to 6 (which are the space and "w" of "world") are removed from the string using the slice! method with a range.
