input
input contains multiple sets of data, and the first line of a number T represents the number of input samples.
Each set of samples starts with a number M
output
Each set of test data outputs a pair of digits, as described above. Two numbers are separated by a space.
Sample Input
The problem defines a new sort algorithm, which is to put a number in a sequence of sequences, if its right number is smaller than itYou can move to the right of the past until the number on the right is larger than it.Easy to get, if the simulation is O (n^2) efficiency, certainly notThinking about it, this problem can be translated intoFor each element in this sequence, the right side of the string is less than its number and, if present, ++ansI did
Title Link: ZOJ 3879 Capture the FlagTest instructions: Given n teams attacking each other server, there are the following rules:1. If team A's server 1 is successfully attacked by Team B, Team A will lose n-1 points, and this n-1 point score will be split equally to other teams that successfully attack team A's server 1.egA total of 4 teamsA B 1C B 1At this point team A and team C both got 1.5 (3/2) points and Team B lost 3 points.2. If a team fails to maintain their servers, the team will lose

Problem descriptionafter repeated attempts, ll finds the greedy strategy is very awful in practice. even there is no apparent evidence to proof it is better than a random one. so he has to drop this strategy and try to discover a better one.
