JieKe08的第1篇题解！

for beginners，特设此题，^_^

#include<bits/stdc++.h>//多美妙的万能头
using namespace std;
int main()
{
    int a,b;//定义变量
    cin>>a>>b;//输入
    cout<<a+b;//输出，最后的换行可有可无
    return 0;//题目给的代码没有这个，但考试最好加上 
}

感谢您花费1分钟阅读鄙人的题解！

#include <iostream>

using namespace std;

int main()
{
int a, b;
cin >> a >> b;
cout << a + b << endl;
}

典型c++算法，大爱noip！

a, b = gets.chomp.split.map(&:to_i)
puts a + b

这是ruby的题解，希望vijos能早日加上ruby的评测机qwq

#include <iostream>
using namespace std;
int main()
{
    int a,b;
    cin>>a>>b;
    cout<<a+b;
    return 0;
}

比较正常的解法（用struct）
#include<iostream>
#include<string>
using namespace std;
struct node
{
string name;
int num;
}q[101];
int n,a,b,c,sum,maxx=0,maxi;
char x,y;
int main()
{
cin>>n;
for(int i=1;i<=n;i++)
{
cin>>q[i].name;
cin>>a>>b>>x>>y>>c;
if(a>80&&c>=1)q[i].num+=8000;
if(a>85&&b>80)q[i].num+=4000;
if(a>90)q[i].num+=2000;
if(a>85&&y=='Y')q[i].num+=1000;
if(b>80&&x=='Y')q[i].num+=850;
sum+=q[i].num;
if(maxx<q[i].num)
{
maxx=q[i].num;
maxi=i;
}
}
cout<<q[maxi].name<<endl;
cout<<q[maxi].num<<endl;
cout<<sum;
return 0;
}

vijos对这道题太仁慈了，数据范围这么小，还没有负数。
我的这个递归算法放到luogu或者openjudge会MLE+TLE。
您现在看到的是史上第一个超时的a+b problem，
卡测评机的新方法，你没有玩过的全新版本。

#include <iostream>
using namespace std;
long long add(long long a,long long b){
    if(a == 0 && b == 0) return 0;
    else if(a == 0 || b == 0){
        if(a == 0 && b > 0) return add(a,b-1)+1;
        else if(a > 0 && b == 0) return add(a-1,b)+1; 
        else if(a < 0 && b == 0) return add(a+1,b)-1;
        else if(a == 0 && b < 0) return add(a,b+1)-1;
    }
    else if(a > 0 && b > 0) return add(a-1,b-1)+2;
    else if(a > 0 && b < 0) return add(a-1,b+1);
    else if(a < 0 && b > 0) return add(a+1,b-1);
    else if(a < 0 && b < 0) return add(a+1,b+1)-2;
}
int main(){
    long long a,b;
    cin>>a>>b;
    cout<<add(a,b)<<endl;
    return 0;
} 

递归版。

#include <iostream>

int add(int a,int b){
    if(a == 0 && b == 0) return 0;
    else if(a == 0 || b == 0){

冷清啊。。我来一发Python3的题解

a, b = map(int, input().split())
print(a + b)

恩 就是这么简洁qwq
