    Guys, the go code won't compile because you guys used strings as a name of a variable in the test code

    GO: your provided code in Go has a bug: you used the name "strings" for a var.

    C# solution

    public static List matchingStrings(List strings, List queries) { List result = new List(); foreach(string wordQuery in queries){ int count=0; foreach(string wordString in strings){ if(wordQuery == wordString){ count++; } } result.Add(count); } return result; }

    C++:

    vector<int> matchingStrings(vector<string> strings, vector<string> queries) {
    map<string, int> fm_queries;
    vector<int> sol;
    for(const auto& q: queries)
    {
        fm_queries[q] = 0;
    }
    
    for(const auto& str: strings)
    {
        if(fm_queries.find(str) != fm_queries.end())
        {
            fm_queries[str]++;
        }
    }
    
    for(const auto& q: queries)
    {
        sol.push_back(fm_queries[q]);
    }
    
    return sol;
    
}

    function matchingStrings(strings, queries) {
   let newarry=[],i,j;
   
   for(i=0; i<queries.length; i++){
    let count=0;
        for(j=0; j<strings.length; j++){
            if(queries[i]===strings[j]){
                count++;
            }
        }
        newarry.push(count);
   }
   return newarry;
