Here, we explored a Python algorithm to find all possible space joins in a given string. By using a recursive approach, we were able to efficiently generate all combinations by including or excluding spaces between the words. This algorithm can be useful in various NLP tasks or any scenario ...
Thestrip()method is useful when dealing with user input as it gets rid of surrounding spaces in the string. This means it doesn’t just remove spaces, it also removes tabs and new line characters, which are all characters we don’t usually want in user-provided strings. There are two mo...
