Problem C. Bear and Up-Down
*****
Please, note the typo in the problem statement, it says: "He is going to choose two indices i < j and swap elements ti < tj in order to get a nice sequence." But it should be: "He is going to choose two indices i < j and swap elements ti AND tj in order to get a nice sequence." THERE IS NO LIMITATION t_i < t_j, YOU SHOULD IGNORE IT
