B'There are n stones arranged on an axis. Initially the i -th stone is located at the coordinate s_i . There may be more than one stone in a single place. You can perform zero or more operations of the following type: You want to move the stones so that they are located at positions t_1, t_2, ldots, t_n . The order of the stones is not important -- you just want for the multiset of the stones resulting positions to be the same as the multiset of t_1, t_2, ldots, t_n . Detect whether it is possible to move the stones this way, and if yes, construct a way to do so. You don 't need to minimize the number of moves. The first line contains a single integer n ( 1 <= n <= 3 cdot 10^5 ) xe2 x80 x93 the number of stones. The second line contains integers s_1, s_2, ldots, s_n ( 1 <= s_i <= 10^9 ) -- the initial positions of the stones. The second line contains integers t_1, t_2, ldots, t_n ( 1 <= t_i <= 10^9 ) -- the target positions of the stones. If it is impossible to move the stones this way, print "NO". Otherwise, on the first line print "YES", on the second line print the number of operations m ( 0 <= m <= 5 cdot n ) required. You don 't have to minimize the number of operations. Then print m lines, each containing integers i, j, d ( 1 <= i, j <= n , s_i <= s_j , 0 <= q 2 cdot d <= q s_j - s_i ), defining the operations. One can show that if an answer exists, there is an answer requiring no more than 5 cdot n operations. Consider the first example. '...
