/**** Method Implementations ****/

//Remove String Method:
std::string removeString(std::string str, std::string rem) {
    //Declare Variables:
    std::string newWord = "";
    int spaces = 0;

    //Add Space To Get Last Word:
    str += " ";

    //Count Spaces:
    for (int i = 0; i < str.length(); i++) {
        if (str.at(i) == ' ') {
            spaces++;
        }
    }
    //Build New Word:
    for (int i = 0; i < spaces; i++) {
        //If Word Iteration != rem:
        if (split(str, ' ')[i] != rem) {
            //Add It To newWord:
            newWord += split(str, ' ')[i] + " ";
        }
    }
    //Return newWord:
    return "\nNew Word: " + newWord + "\n\n'" + rem + "' has been removed\n";
}

//Remove Char Method:
std::string removeChar(std::string str, char rem) {
    //Declare Variable:
    std::string newWord = "";

    //Traverse str:
    for (int i = 0; i < str.length(); i++) {
        //If Iteration != rem:
        if (str.at(i) != rem) {
            //Add It To newWord:
            newWord += str.at(i);
        }
    }
    //Return newWord:
    return "\nNew Word: " + newWord + "\n\nAll '" + rem + "'s have been removed\n";
}


//Split String Method:
std::vector<std::string> split(std::string str, char breakOn) {
    //Declare Variables:
    std::vector<std::string> sVec;
    std::string statement = "";

    //Traverse str:
    for (unsigned int i = 0; i < str.size(); i++) {
        //If Iteration != breakOn:
        if (str.at(i) != breakOn) {
            //Add It To statement:
            statement += str.at(i);
        }
        //If Iteration == breakOn:
        else if (str.at(i) == breakOn) {
            //Push Vector With statement
            sVec.push_back(statement);
            //Reset Statement:
            statement = "";
        }
    }
    //Return sVec:
    return sVec;
