Test instructionsTwo trees (10^5 nodes) ask how many of them are isomorphic to each otherIdeas:The isomorphism of a tree is generally judged by a hash.The hash function is 1, val=a 2, val = (val*p) ^soni%q where Soni is the hash value of the sub-tree 3, Val=val*b%qNote that the son value should be sorted (this is because the left and right subtrees are separated so they do not have to be sorted)Code:#include ZOJ 3602 Count the Trees
