    Description

    Iahub and Iahubina went to a date at a luxury restaurant. Everything went fine until paying for the food. Instead of money, the waiter wants Iahub to write a Hungry sequence consisting of n integers.

    A sequence a1a2, ..., an, consisting of n integers, is Hungry if and only if:

    • Its elements are in increasing order. That is an inequality ai < aj holds for any two indices i, j (i < j).
    • For any two indices i and j (i < j), aj must not be divisible by ai.

    Iahub is in trouble, so he asks you for help. Find a Hungry sequence with n elements.

    Input

    The input contains a single integer: n (1 ≤ n ≤ 105).

    Output

    Output a line that contains n space-separated integers a1 a2, ..., an (1 ≤ ai ≤ 107), representing a possible Hungry sequence. Note, that each ai must not be greater than 10000000 (107) and less than 1.

    If there are multiple solutions you can output any one.

    Sample Input

    Input
    3
    Output
    2 9 15
    Input
    5
    Output
    11 14 20 27 31

    思路:本来想打素数表, 但不能超过十的七次方应该就是卡素数吧, 直接把数让他从最大开始然后需要多少连续输出多少,最多十的五次方个数, 但最大十的七次方, 这中间肯定不会出现整除的。


    代码:

    #include<stdio.h>
    #include<string.h>
    #include<math.h>


    #define N 10000000

    int main(void)
    {
    int i, n;
    while(scanf("%d", &n) != EOF)
    {
    for(i = N - n + 1; i <= N; i++)
    {
    if(i == N)
    printf("%d ", i);
    else
    {
    printf("%d ", i);
    }
    }
    }


    return 0;
    }
