Note
In the first example, there are 55 participants. The Cossack has 88 pens and 66 notebooks. Therefore, he has enough pens and notebooks.
In the second example, there are 33 participants. The Cossack has 99 pens and 33 notebooks. He has more than enough pens but only the minimum needed number of notebooks.
In the third example, there are 88 participants but only 55 pens. Since the Cossack does not have enough pens, the answer is “No”.
题意：有a个人，b只钢笔，c本笔记本，判断是否每个人都可以拿到钢笔与笔记本。
思路：只需比较a与b,c的大小关系即可。
#include<stdio.h>
int main()
{
int a,b,c;
while(~scanf("%d%d%d",&a,&b,&c)){
if(a<=b&&a<=c)
printf("YES\n");
else printf("NO\n");
}return 0;
