instacart order minimum

I'm bored with it .. In fact, the key to this question is not the method of reverse order, because it is also possible to use brute force. To give a sequence with the length of n (n I use array a [0 ~ N-1] to store raw data. You only need to find the sum of the reverse order of the original sequence, and then for each order of a [I] (0 1. Violence Law.

together, output the method in the following fomat: I1J1I1J1 ...... WhereIk Ik(K> = 1) are the identification numbers of the two computers to be connected. all the integers must be separated by a space and there must be no extra space at the end of the line. if there are multiple solutions, outputLexicographically smallestOne (see hints for the definition"Lexicography small") If you cannot connect them, just output"-1 "in the line.

Of course, in my blog There are also wired and tree arrays to find the reverse number of the template;Here I do not discretization, but not all the reverse number of templates ...I recommend a blog with a very detailed illustration of what I don't know about merge sort;

Question: Click to open the link ThemeReturns the longest return string of a string. If multiple results exist, the minimum Lexicographic Order is output. IdeasWe all know that we can calculate the maximum length of a string in the descending order of a string and the longest common subsequence of the original string.However, this question should not only be ou

Otherwise, the first line contains a single number T, which was the minimal number you had got, and if T is not zero, the Second line was needed, which contains t integers in ascending order that indicate the number of people who meet bad things .

search, the reverse order ensures the minimum Lexicographic Order, Therefore, in the reverse direction, it will first expand to AAA and find the solution. Break is obviously faulty, Obviously, this Lexicographic Order is not necessarily the smallest, and the results of the first half are not taken into account. So we

But this problem is not only to output palindrome string, but also r
