I partly agree with this. Still, the problem set has statistics and solving a large number of problems is a great achievement. It would not make sense that you can reach a top place by sending other people's solutions. →Reply BD_SM ...
If you’ve already started working on your solutions — take a quick look to make sure your task wasn’t affected. The logic remains unchanged; the updates are purely textual. UPD 2:We’re aware that some participants have explored ways to pass the tests without fully implementing all the ...
Your solution (你的提交编号) for the problem (题目编号) significantly coincides with solutions (用户名)/(提交编号). Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use Loading... with the default settings (public access...
Thus, you can hack somebody else's solution and earn points through it. After the contest all the solutions that have passed the pretests and haven't been hacked are tested on the final set of tests. The value of a task decreases during the contest (the faster you solve the problem, ...

In this problem you should implement the similar functionality. You are given a string which only consists of: uppercase and lowercase English letters, underscore symbols (they are used as separators), parentheses (both opening and closing). ...
Second sample: One of optimal solutions is to send one student to remove a box from the first pile and a box from the third pile, and send another student to remove a box from the third pile. Overall,5 seconds. Third sample: With a lot of available students, send three of them to ...
OutputIn the first line print a single integer — the number of brackets «[» in the required bracket sequence. In the second line print the optimal sequence. If there are more than one optimal solutions print any of them.Examples ...
Output If there is no solution to the problem, print -1. Otherwise print four space-separated integers that correspond to the coordinates of the two other trees. If there are several solutions you can output any of them. Note that
