from HTMLParser import HTMLParser

class MyHTMLParser(HTMLParser):
    def handle_comment(self, data):
        if "n" in data:
            print ">>> Multi-line Comment"
        else:
            print ">>> Single-line Comment"
        print data
    def handle_data(self, data):
        if len(data.strip())>0:
            print ">>> Data"
            print data

html = ""       
for i in range(int(raw_input())):
    html += raw_input().rstrip()
    html += 'n'
    
parser = MyHTMLParser()
parser.feed(html)
parser.close()
