B'You are given n elements numbered from 1 to n , the element i has value a_i and color c_i , initially, c_i = 0 for all i . The following operation can be applied: Find the maximum value of sum limits_{i=1}^n{c_i} that can be obtained after applying the given operation any number of times. The first line contains an integer n ( 3 <= q n <= q 2 cdot 10^5 ) -- the number of elements. The second line consists of n integers a_1, a_2, ... , a_n ( 1 <= q a_i <= q n ), where a_i is the value of the i -th element. Print a single integer in a line -- the maximum value of sum limits_{i=1}^n{c_i} that can be obtained after applying the given operation any number of times. In the first test, it is possible to apply the following operations in order: '...
