Which XXX and YYY correctly output the smallest values? Vector user Vals contains integers (which may be positive or negative). Choices are in the form XXX/YYY. // Determine smallest (min) value int minval; XXX for (i = 0; i < uservals. size(); ++i) { if (YYY) { minval - userVals. at(i); cout << "Min: " << minval << endl; minval - uservals. at(); /uservals. at(i) < minval minval = 0; /userval > minval minval - uservals. at(); /uservals. at(i) > minval minval - 0; /userval < minval
