Now it's easy to make somebody win x x times and then let the next challenger be the winner for x x rounds and so on (it's simpler if 2 wins at first, so the winners are all gonna have ids of the form 2 ix 2 i x).

The problem with option 1 is calculating y for every mismatch, so you have to count the number of mismatches taken by the first option and divide them by 2 , to avoid that, you can just multiply the second option (x) by 2 and divide the final solution by 2. 在一个数组中，可以使用最多n次操作，选择两个数字，若两数加起来为奇数，则将位置靠后的数字改为另一个数；若为偶数，则将位置靠前的数改为前一个数，怎样操作使得在最多n次操作之后使数列变为非递减排序的。 思路：一般这种题还有什么交互题，都应该去考虑比较极端的情况。 这个题可以这样考虑：将第一个数和最后一个数经过一次操作变成一样的，中间的数，如果加起来是奇数的话选第一个数，如果加起来是偶数的话选最后一个数，这样在n 1次操作后将整个序列变成一样的数字，满足条件。 （注意1特判，也可能不用？ ac code： std::ios:: sync with stdio (false);.
