Taco Word Lengths

This problem requires you to count the lengths of words in a given string. The input string will contain words separated by spaces and may include punctuation. Your task is to output a JSON object where each key is a lowercase word (with punctuation removed) and its value is the length of that word. For example, processing Hello world! should produce {"hello":5, "world":5}.

Words are identified using the regular expression \(\texttt{\b\w+\b}\) in \(\LaTeX\) format. Note that if a word appears multiple times, it should only appear once in the output. The keys in the resulting JSON object must be sorted in alphabetical order.

outputFormat
