题解

根据公式计算即可，注意保留四位小数。

#include <bits/stdc++.h>
using namespace std;
using ll =long long;

int main ()
{
	int n,i; cin>>n;
	vector<double> v(n);
	double minn=100,maxn=-100;
	for(i=0;i<n;i++)
	{
		cin>>v[i];
		minn=min(minn,v[i]);
		maxn=max(maxn,v[i]);
	}
	for(i=0;i<n;i++)
		cout<<(fixed)<<setprecision(4)<<(v[i]-minn)/(maxn-minn)<<" ";
	return 0;
}
