难么？
#include <bits/stdc++.h> using namespace std; int RAND_1(long long a,long long b){ long long n = a + b; cout << n; return 0; } int RAND_2(string a, string b, int n[500], int m[500], int ans[501]){ for(int i = 0; i < a.size(); i++) n[i] = a[a.size() - i - 1] - '0'; for(int i = 0; i < b.size(); i++) m[i] = b[b.size() - i - 1] - '0'; int len_maxn = max(a.size(), b.size()) + 1; for(int i = 0; i < len_maxn; i++) { ans[i] = n[i] + m[i] + ans[i]; if(ans[i] > 9) { ans[i + 1]++; ans[i] = ans[i] % 10; } } while(ans[len_maxn - 1] == 0 && len_maxn > 0) len_maxn--; for(int i = len_maxn - 1; i >= 0; i--) cout << ans[i]; return 0; } int n[500], m[500],c[501]; int main(){ long long a , b; int x; x = 1 + rand() % 2; if(x == 1){ cin >> a >> b; RAND_1(a,b); } string z , y; if(x == 2){ cin >> z >> y; RAND_2(z , y , n , m, c); } return 0; }2024-11-10 来自 北京
3不如这个
#include<cstdio> inline int read(){ int x=0,c; while((c=getchar_unlocked())<'0'); do x=x*10+c-'0'; while((c=getchar_unlocked())>='0'); return x; }inline void write(int n) { if(n<0) { putchar('-'); n*=-1; }if(n>=10){ write(n/10); }putchar(n%10+'0'); }int main(){ write(read()+read()); return 0; }2025-09-19 来自 上海

#include<iostream>
using namespace std;
int main()
{
int a,b;
cin>>a>>b;
cout<<a+b;
return 0;
}
???
好难！！！！
难的只有9行！？2026-01-03 来自 江苏
2我4行：
#include <bits/stdc++.h>
int main(){
long long a,b; stdcin>>a>>b; stdcout<<a+b;

2#include<bits/stdc++.h>//导入万能头文件
using namespace std;//命名空间
int main(){
//主函数
int a,b

cin>>a;
cout<<a+b
//输出
return 0;
//结束程序
