Problem 60237. Finding the Most Frequent Letter in a Text

You are given a text containing various English letters, digits and punctuation symbols. Your task is to find the most frequently occurring letter in the tex.
The letter returned must be in lower case.
Rules:
  • While checking for the most wanted letter, casing does not matter; therefore, 'A' is equivalent to 'a'.
  • If two or more letters have the same frequency, return the letter that comes first in the Latin alphabet. For instance, in the word 'one', the letters 'o', 'n' and 'e' occur once each. Therefore, 'e' is chosen as it comes last in the Latin alphabet.
  • Ignore punctuation symbols, digits, and whitespaces.
Example: in the text 'Hello World!', the most frequent letter is 'l'.
