思路就是我们从1枚举到 ( n ) \sqrt(n) ( n)如果能整除我们就放进map容器中最后遍历容器就好了
代码#include
using namespace std;
//----------------自定义部分----------------
#define ll long long
#define mod 1000000007
#define endl "\n"
#define PII pair
#define INF 0x3f3f3f3f
int dx[4] = {-1, 0, 1, 0}, dy[4] = {0, 1, 0, -1};
ll ksm(ll a,ll b) {
ll ans = 1;
for(;b;b>>=1LL) {
if(b & 1) ans = ans * a % mod;
a = a * a % mod;
}
return ans;
}
ll lowbit(ll x){return -x & x;}
const int N = 2e6+10;
//----------------自定义部分----------------
int t,n,m,q,a[N];
void slove(){
map vis;
cin>>n;
for(int i = 1;i * i
