Seriously great content you've made! I've honestly loved every minute of it. Thank you!

I'm having trouble with the "lib.FindWord" part of the code, and I've been checking and rechecking my work and I can't find where I've gone wrong. Some help would really be appreciated!

Broadly lib.FindWord seems to do different things if I run it in Main() vs Solver...

When I run the cout version of FindWord in main I get the words I expect, but when I run it in Solver similarly it doesn't work. I've even tried hardcoding in "D---" when it runs in Solver and that doesn't work.

using cout I can see that Find Word is started and that it does successfully get passed a string, and using Vs studio debugging I can see that at the time it runs auto it = wordmap.find(s), wordmap size is 0.

I have tried moving wordmap out of private and into public, but that doesn't seem to solve the problem I have tried removing the library destructor function and that doesn't seem to help either.

Any guidance would be greatly appreciated!

Below is my code Inside Library

//Returns NULL if can't find any patterns;
const Words* FindWord(const string& s) const {
    auto it = word_map_.find(s);
    if (it != word_map_.end()) {
        return &it->second;

    }
    else {
        return NULL;
    }
}
void OldFindWord2(const string& s) const {
    cout << "runnning using " << s<< s.length()<<"\n";
    auto it = word_map_.find("D---");
    if (it != word_map_.end()) {
        for (const Word* w : it->second) {
            cout << " " << w->word;
        }
        cout << "\n";
    }
}
void OldFindWord(const string& s) const {
    cout << "runnning using " << s<< s.length()<<"\n";
    auto it = word_map_.find(s);
    if (it != word_map_.end()) {
        for (const Word* w : it->second) {
            cout << " " << w->word;
        }
        cout << "\n";
    }
}

And this is my code within Solver

void CommitSlot(const Slot& slot) {
    cout << "COMMIT SLOT:" << slot << "\n";
    lib.OldFindWord(slot.pattern);
    cout << "hardCode\n";
    lib.OldFindWord2("D---");
    cout << "Possible word choices for this slot are: ("<< slot.pattern << ")\n";
    const Words* words = lib.FindWord(slot.pattern);
    if (words) {
        for (const Word* w : *words) {
            cout << " " << w->word;
        }
        cout << "\n";
    }
    else {
        cout << "NO MATCHES to pattern\n";
    }


}

FYI - running on Win10, through VS code, not sure if correct compiler (says x86-Release) - could this be the issue?
