Little girl Susie went shopping with her mom and she wondered how to improve service quality.

There are n people in the queue. For each person we know time ti needed to serve him. A person will be disappointed if the time he waits is more than the time needed to serve him. The time a person waits is the total time when all the people who stand in the queue in front of him are served. Susie thought that if we swap some people in the queue, then we can decrease the number of people who are disappointed.

Help Susie find out what is the maximum number of not disappointed people can be achieved by swapping people in the queue.

Input

The first line contains integer n (1 ≤ n ≤ 105).

The next line contains n integers ti (1 ≤ ti ≤ 109), separated by spaces.

Output

Print a single number — the maximum number of not disappointed people in the queue.

515 2 1 5 3

output

4

Note

Value 4 is achieved at such an arrangement, for example: 1, 2, 3, 5, 15. Thus, you can make everything feel not disappointed except for the person with time 5.

解题说明：此题类似于之前做过的排队接水，只要保证耗时最短的人排在前面就能让总等待时间最短，排序即可。

#include<iostream>#include<algorithm>using namespace std;int main(){int a[200005],n,i;cin>>n;for(i=0;i<n;i++){cin>>a[i];}sort(a,a+n);int s=0,c=0;for(i=0;i<n;i++){if(a[i]>=s){c++;s=s+a[i];}}cout<<c<<endl;return 0;}
