Alicia has a huge garden, which is the habitat of many animals that she really cares about. After listening to a podcast about biodiversity, she becomes very concerned about the balance between species in her garden. She wants to know if there is a species that could overtake the others. To do so, she decides to carry out a census of all the animals in the garden, writing down the species of each of them. Can you help her check if there are strictly more animals from one species than there are from all the other species together? \InputFile The first line contains the number of animals $n~(1 \le n \le 2 \cdot 10^5)$; Each of the next $n$ lines contains an animal as a string of length at most $20$, containing only ASCII alphanumeric characters. \OutputFile Print a string that appears a number of times that is greater than the sum of the others, if there is any, or the string "\textbf{NONE}" otherwise.
