Remove leading and trailing whitespace in Julia

To remove leading and trailing whitespaces from a string in Julia, you can use the strip() function. Here's an example:

# Original string with leading and trailing whitespaces
original_str = "   Hello, world!   "
# Remove leading and trailing whitespaces

new_str = strip(original_str)
# Output the new string

println(new_str)

This will output "Hello, world!" with the leading and trailing whitespaces removed.

You can also specify which characters to remove from the beginning and end of the string by passing them as arguments to the strip() function. For example:

# Original string with leading and trailing periods
original_str = "...Hello, world!..."
# Remove leading and trailing periods

new_str = strip(original_str, '.')
# Output the new string

println(new_str)

This will output "Hello, world!" with the leading and trailing periods removed.
