Analysis:It looks like the team can do it, but the data range is for the card, so we consider another way of doing it offline.First for each flower, find the next occurren

Given two sequences, ask what is the difference or maximum of one value from each of the two sequences
Think of the numbers in a sequence as a binary 01 string, and then into the trie tree.Then the number of the B sequence is also treated as a 01-string, and then in the trie tree from high to low greedy to findIf the current bit of the 01 string found in the B sequence is 0, find the son of the trie tree that is 1Or you can only go to the right son of 0, and vice versa, th
integer Wi indicates the weight of the i-th.Then M lines follow. Each line represents a query. It contains integers L and R, meaning the king wanted to ask about the situation if he sent all rabbits from the L-th one to the r-th one into prison.(1 The input ends with n = 0 and M = 0.OutputFor every query, output one line indicating the answer.Sample Input3 22 1 41 21 36 43 6 1 2 5 31 34 64 42 60 0Sample Output211312HintIn the second case, the answer of the 4-th query are 2, because only 1 and 5
