This solution is based on the fact that if we're on the right path to the optimal string, the number of invalid parentheses must always decrease. Time complexity: In the worst case, I could have some input like ")))", where I need to search through the entire string. The good thing...

Python also requiresdictionarykeys to be unique: print({10:"Integer 10",10.0:"Float 10"})print({True:"Boolean True",1:"Integer 1"}) The dictionaries in this code contain equal keys. Only the first key is retained. However, its value is replaced by the last value added to the dictiona...

In this lesson we have learned how to remove empty values from the array. We can remove the empty values from the string using array_filter() function
Ultimately, the choice of method depends on the specific requirements of your task, the complexity of the patterns you’re dealing with, and your preference for readability and conciseness. Related Article - Python String
