       题意：给两个数n和d，然后输入n个数，问最少要删掉几个数才能让剩下的n个数的任意两个数相差不大于d

AC代码：#include <iostream>
#include <cstdio>
#include <algorithm>
#define MAXN 105
#define MAX(a,b) a>b?a:b
using namespace std;
int n,d,mx;
int pre[MAXN];

int main()
{
mx = -1;
scanf("%d%d",&n,&d);
for(int i=0;i<n;i++) scanf("%d",&pre[i]);
sort(pre,pre+n);
for(int i=0;i<n;i++){
for(int j=i;j<n;j++){
if(pre[j] - pre[i] <= d){
mx = MAX(mx,j-i+1);
}
}
}
printf("%d\n",n - mx);
return 0;
}
