Rank the Search Terms

Basic

A search-indexing step needs to know how often each term appears in a document so it can rank relevance.

Implement `solve(List<String> words)` to return a map of each distinct word to how many times it appears.

Examples

Input["a", "b", "a", "c", "a", "b"]

Output{a=3, b=2, c=1}

Input["x"]

Output{x=1}

Hints

Read the current count (0 if absent) and store count + 1.

Map<String, Integer> solve(List<String> words) {
    // return word -> count
    return null;
}
