The most frequent letter

Given a text we want to know the most frequent lowercase letter. Write a program that given a text prints the most frequent lowercase letter and its frequency among all lowercase letters. You can use the method islower() to check if a character is a lowercase letter. For instance, all threee expressions ’=’.islower(), ’9’.islower() and ’A’.islower() evaluate to False. On the contrary, ’a’.islower() is True.

Input

Input is a text of characters. The input text has at least one lowercase letter.
