Summarize a batch
Difficulty: Easy
Given a list of strings, return a dictionary with total and blank counts. A blank record contains only Unicode whitespace or is empty. Preserve the input list.
Examples
[]{'blank': 0, 'total': 0}['a', ' ', '']{'blank': 2, 'total': 3}['\t', '0', '\u2003']{'blank': 2, 'total': 3}Constraints
Use only Python standard-library modules. Inputs contain at most 1,000 records and 100,000 characters unless stated otherwise. Do not mutate input objects. Return the specified JSON-compatible value; do not print it.
