Words in text are separated by spaces (possibly several). Return a dictionary (JavaScript: object) mapping each word, in lower case, to how many times it appears.

Examples

Input: text = "The cat and the hat"
Output: {"the": 2, "cat": 1, "and": 1, "hat": 1}
Input: text = ""
Output: {}

Examples use JSON: true/false/null are True/False/None in Python.
