CF959D Mahmoud and Ehab and another array construction task 数学

Mahmoud has an array a consisting of n integers. He asked Ehab to find another array b of the same length such that:

• b is lexicographically greater than or equal to a.
• b_i ≥ 2.
• b is pairwise coprime: for every 1 ≤ i < j ≤ n, b_i and b_j are coprime, i. e. GCD(b_i, b_j) = 1, where GCD(w, z) is the greatest common divisor of w and z.

Ehab wants to choose a special array so he wants the lexicographically minimal array between all the variants. Can you find it?

An array x is lexicographically greater than an array y if there exists an index i such than x_i > y_i and x_j = y_j for all 1 ≤ j < i. An array x is equal to an array y if x_i = y_i for all 1 ≤ i ≤ n.

Input

The first line contains an integer n (1 ≤ n ≤ 10⁵), the number of elements in a and b.

The second line contains n integers a₁, a₂, ..., a_n (2 ≤ a_i ≤ 10⁵), the elements of a.

Output

Output n space-separated integers, the i-th of them representing b_i.

Input

Copy

3
10 3 7

Output

Copy

10 3 7 

Note

Note that in the second sample, the array is already pairwise coprime so we printed it.

求一个互素的序列且字典序比 A 序列大的最小序列；

显然，当某一位置的 b[ i ]> a[ i ] 时，我们只需要安排剩下的数使得 b 数列互素即可；

那么这个我们可以用 fg 来标记一下；

如何保证我们的序列互素呢？考虑质因子，

我们用 use 来看最小质因子是否有使用，如果已经使用，那么显然不能选用；

using namespace std;

#define maxn 200005

bool judge(int x)
{
    // 检验 x 是否有已经用过的质因子
    int num[60],cnt=0;
    while(vis[x]){
        num[++cnt]=pre[x];x/=pre[x];
    }
    num[++cnt]=x;
    for(int i=1;i<=cnt;i++){
        if(use[num[i]])return false;
    }
