Move Zeroes 题目: Given an array nums, write a function to move all 0‘s to the end of it while maintaining the relative order of the non-zero elements. For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0…

[CF653G]Move by Prime 题意:给你一个长度为n的数列$a_i$,你可以进行任意次操作:将其中一个数乘上或者除以一个质数.使得最终所有数相同,并使得操作数尽可能小.现在我们想要知道$a_i$的所有子序列的操作数之和是多少.答案对$10^9+7$取模. $n,a_i\le 3\times 10^5$ 题解:显然要对每个质数分别处理.而对于每个质数,最终一定是让所有数都变成该序列的中位数最优.因此如果所有数的次数分别是$k_1,k_2...k_n$,则如果i在中位数左边,则贡献为$…
