cf 443 D. Teams Formation(细节模拟题) 题意: 给出一个长为\(n\)的序列,重复\(m\)次形成一个新的序列,动态消除所有k个连续相同的数字,问最后会剩下多少个数(题目保证消除的顺序对答案不会造成影响) \(n <= 10^{5} ,m <= 10^{9} ,k <= 10^{9},a_i <= 10^{5}\) 思路: 直接上题解好了 首先要用栈预处理序列本身,然后考虑处理后的序列 比较头和尾是否能够消除,细节需要处理好. #include<bi…

题意 给定$n$个数,重复拼接$m$次,相邻$k$个重复的可消除,问最后序列中有多少个数 首先可以发现当$k>=n$时,如果要使$n$个数可以被消除,那么$n$个数必须一样,否则$n$个数不能被消除 当$k<n$时,首先对序列能够消除的消除,用栈记录每个数和这个数的相同的相邻个数$f$,将序列压缩,考虑一次拼接,记$L$为第二个序列的开始元素,$R$为第一个序列的最后一个元素,如果$L!=R$那么所有序列将不能压缩,如果$L==R,f_L+f_R!=k$,那么这两个序列拼接之后会合并成一个不可…
