浅浅地刷下题

比较细

#include <bits/stdc++.h>
using namespace std;
int n,a,maxn,minn;
int main()
{
	maxn=-100001;
	minn=100001;
	cin>>n;
	for(int i=1;i<=n;i++)
	{
		cin>>a;
		if(a<-100000 || a>100000)
		{
			cout<<endl<<a<<"超出了100000或-100000，不计算";
			continue;	
		}
		maxn=max(maxn,a);
		minn=min(minn,a);
		
		
	}
	cout<<endl<<endl<<minn<<" "<<maxn;
	return 0;
	
}

#include<iostream>
using namespace std;
int n,ax,in;
int main(){
	int n,x,ax=-100001,in=100001;
	cin>>n;
	for(int i=1;i<=n;i++){
		cin>>x;
		ax=max(ax,x);
		in=min(in,x); 
	}
	cout<<in<<" "<<ax;
	return 0;
}

# include <bits/stdc++.h>

using namespace std;
const int N=1e5+10;
int a[N],n;
bool cmp(int a,int b){return a>b;}
int main(){
	cin>>n;
	for(int i = 1;i<=n;i++)cin>>a[i];
	sort(a+1,a+n+1,cmp);
	cout<<a[n]<<" "<<a[1]<<endl;
	return 0;
}
```
`

#include <stdio.h>
#include <iostream>
using namespace std;
int main()
{
	int n,x;
	cin >> n;
	int minn , maxx;
	minn = 10000000;
	maxx = -1000000;
	for(int i=0; i < n; i++)
	{
		cin >> x;
		if(x >maxx)
		{
			maxx = x;
		}
		if(x < minn)
		{
			minn = x;
		}
	}
	cout << minn << ' ' << maxx << endl;
}

用sort排序就可解决 #include<bits/stdc++.h> using namespace std;

const int N = 1e5 + 5;

int a[N],n; bool cmp(int a,int b) { return a>b; } int main() { cin>>n; for(int i=1;i<=n;i++)cin>>a[i]; sort(a+1,a+1+n,cmp); cout<<a[n]<<" "<<a[1]; return 0; }

//大佬救我，帮我看看问题出在哪里 #include #include <math.h> using namespace std; int main() { int n,a; cin >>n; int max =-100001; int min = 100001; for(int i = 0;i < n; i++) { cin >> a; if( min > a) min = a; else if(max < a) max = a; } cout << min <<" "<< max << endl; }

*，这水题竟然提交了3次才过😕 。。。 AC代码：

#include<iostream>
using namespace std;
long long n,x,maxn=-100000,minn=100000;
int main(){
	cin>>n;
	for(int i=1;i<=n;i++){

		minn=min(minn,x);
	}
	cout<<minn<<" "<<maxn;
	return 0;
}

测试点1，测试点6 maxn和minn都一样

    maxx = -1000000;
	for(int i = 0 ; i < n ; i++)
	{
		cin >> x;
		if(x > maxx)
		{
			maxx = x;

		if(x < minn)
		{
			minn = x;

		if(x<minn)
		{
		minn=x;
		}
	}
	cout<<minn<<" "<<maxx;
}

    {

        if(x > maxx)
        {
            maxx = x;
        }
        if (x <minn)
        {
            minn = x;

        }


    }
    cout << minn << " " << maxx << endl;
