Language/Type: C++ collections map STL

Write the output produced by the following function when passed each of the following maps. Assume that a map displays in {key:value, key:value, ..., key:value} format.

void collectionMystery5(map<string, int>& m1, map<int, string>& m2) {
    map<string, string> result;
    for (auto kv : m1) {
        if (m2.find(kv.second) != m2.end()) {
            result[kv.first] = m2[kv.second];
    cout << result << endl;
m1: {"bar":1, "cat":2, "foo":3, "mum":4}, m2: {1:"earth", 2:"wind", 3:"air", 4:"fire"}
m1: {"five":105, "four":104, "one":101, "six":106, "three":103, "two":102}, m2: {99:"uno", 101:"dos", 103:"tres", 105:"cuatro"}
m1: {"a":42, "b":9, "c":7, "d":15, "e":11, "f":24, "g":7}, m2: {1:"four", 3:"score", 5:"and", 7:"seven", 9:"years", 11:"ago"}
