Farmer John's farm consists of NN pastures (2≤N≤1052≤N≤105) connected by N−1N−1 roads, so that any pasture is reachable from any other pasture. That is, the farm is a tree. But after 28 years of dealing with the tricky algorithmic problems that inevitably arise from trees, FJ has decided that a farm in the shape of a tree is just too complex. He believes that algorithmic problems are simpler on paths.Thus, his plan is to partition the set of roads into several paths, and delegate responsibility for each path to a worthy farm hand. To avoid contention, he wants each path to be the same length. He wonders for which lengths there exists such a partition.

More precisely, for each 1≤K≤N−11≤K≤N−1, help Farmer John determine whether the roads can be partitioned into paths of length exactly KK.

SCORING:

• In test cases 2-4 the tree forms a star; at most one vertex has degree greater than two.
• Test cases 5-8 satisfy N≤103N≤103.
• Test cases 9-15 satisfy no additional constraints..

INPUT FORMAT (file deleg.in):

The first line contains a single integer NN.The next N−1N−1 lines each contain two space-separated integers aa and bb describing an edge between vertices aa and bb. Each of aa and bb is in the range 1…N1…N.

OUTPUT FORMAT (file deleg.out):

Output a bit string of length N−1.N−1. For each 1≤K≤N−1,1≤K≤N−1, the KKth bit of this string from the left should equal one if it is possible to partition the edges of the tree into paths of length exactly KK and 00 otherwise.

It is possible to partition this tree into paths of length KK for K=1,2,**3.**K=1,2,3. For K=3K=3, a possible set of paths is as follows:

13−12−11−8,10−9−8−6,7−6−2−3,5−4−2−1
