Word Frequency Counter

Problem Implement word_frequency(text): given a string, return a dictionary mapping every word to its number of occurrences. For this problem, a word is a whitespace-delimited token. Matching is case-sensitive, and punctuation attached to a token remains part of that token. For example: the cat sat on the mat returns: {"the": 2, "cat": 1, "sat": 1, "on": 1, "mat": 1} Input Format Standard input contains one line, text. Output Format Print words in order of first appearance, one per line as word count. Constraints text has length at most 10^6. Example Input: the cat sat on the mat Output: the 2 cat 1 sat 1 on 1 mat 1 Example Input
