题意:有最多10000次操作,在一个初始为空的数列中添加或移除元素并保持数列有序,每次操作后,如果数列个数为奇数就输出中间值,如果为偶数就输出中间两个值得平均值。
思路:刚开始写了一发multiset模拟,看吴琦TLE了估计他也是multiset写的,就...

昨天 yep 问了一个问题:
For two positive integers a and b, the Ulam sequence U(a,b) is defined by U(a,b)1 = a, U(a,b)2 = b and for k > 2, U(a,b)k is the smallest integer greater
than U(a,b)(k-1) which can...
