In Julia, you can remove parts of a string using the replace() function or indexing.
1. Using replace(): You can use the replace() function to remove a specific substring from a string by replacing it with an empty string. The syntax is as follows:
new_string = replace(original_string, substring_to_remove, "")
Here's an example:
original_string = "Hello, world!"
substring_to_remove = "world"
new_string = replace(original_string, substring_to_remove, "")
println(new_string) # Output: "Hello, !"
2. Using indexing: You can also remove a specific portion of a string using indexing. The syntax is:
new_string = old_string[begin:index_to_remove-1]*old_string[index_to_remove+length_of_substring:end]
Here's an example:
old_string = "Good morning, everyone!"
index_to_remove = 14
length_of_substring = 9
new_string = old_string[begin:index_to_remove-1]*old_string[index_to_remove+length_of_substring:end]
println(new_string) # Output: "Good morning, !"
Note that the begin is optional since it represents the first index.
