pythonprogramminglanguage Output: g To find the most frequent character in the string, we will count the frequency of all characters in the string and then extract the character with maximum frequency. To store characters and their frequencies, we will use a dictionary. Python provides different m...

This process involves creating a dictionary wherein keys become the sorted tuples; values remain as original tuples. Subsequently, we incorporate the sorted tuple into the dictionary as a key; simultaneously, we assign its corresponding value-the original tuple. Example Open Compiler data = [(1,...
