思路: 把给定的数分解质因子之后,对于每一个质因子x,都需要x次操作(一次copy all操作和x-1次paste),所以答案就是对分解后的所有质因子求和. 实现: class Solution { public: int minSteps(int n) { ; ; i <= n; i++) { ) { sum += i; n /= i; } } return sum; } };…

LeetCode每日一题2021.9.19 跳转链接 分析 我们发现每个数字只能由它的因数通过复制而来, 因为复制操作是每次去添加一个相同的个数. 因此我们就可以得出DP方程 dp[i] = min({dp[i], dp[i/j] + j, dp[j] + i/j}) 因为我们直接两重循环进行状态转移即可 const int N = 1010; class Solution { public: int f[N] = {0}; int minSteps(int n) { memset(f, 0x3…
