Keep in mind that the things are counted in regularity delivery include word-tag frames. Since words and tickets is matched, we are going to deal with your message as a condition and the label as a meeting, and initialize a conditional frequency submission with a long list of condition-event pairs. This lets us all notice a frequency-ordered set of tags furnished a word:
