Last year we have participated in a football tournament. In this tournament, the committee divided total players into two categories one is junior player and another is senior player. They have followed the rules for deciding a player is junior or senior. If age of a player is less than 20 years then he is a junior player and otherwise he is a senior player.
There are several lines of input. Each line containing an integer denotes the age of a player. Input is terminated by EOF.
For each line of input you should print “junior” or “senior” in a line by following the description above.
