Walkthrough

A new Go file introduces the CountWordFrequency function that normalizes input text by lowercasing and removing apostrophes, tokenizes by splitting on non-letter and non-digit boundaries, and returns a map of each token to its occurrence count.

Changes

Word Frequency Counting

Layer / File(s)	Summary
CountWordFrequency function challenge-6/submissions/sreehari-k-19/solution-template.go	The exported CountWordFrequency(text string) map[string]int function normalizes input by converting to lowercase and removing apostrophes, then tokenizes the text by splitting on non-alphanumeric boundaries and counts the frequency of each resulting token in a returned map.

Poem

🐰 A rabbit counts words with glee,
Stripping apostrophes free,
Lowercased tokens in a map,
Frequencies tabbed without a gap!
Simple, swift, and clean—what a snap! 🐇
