In Python (and many other languages), there is True, and there are truthy values. That is, values interpreted as True if you run bool(variable). Similarly, there is False, and there are falsy values (values that return False from bool(variable)). An empty list ([]), string (""),...
It is important to note that when the string is empty, the value oflastIndexwill be -1, which requires appropriate handling in your code. Solution 2: The provided responses involve removing excess characters from the string and generating a modified string with adjusted indices, resulting in an...

object to compare objects by their values rather than by reference. This method is much faster than searching through a Map. Another solution is to use the Map to access the array value for the key, and then use the normal Array method to check if the specific string is contained in it...
developing solutions that already exist. However, this common practice is why hackers exploit dependencies to wreak havoc in our software, and why we need to be able to detect when something is amiss. As such, we use tools likeBandit, an open-source security analysis utility for Python ...
