深度太高炸了。

考虑以下输入:
1000000000 1000000000
-1 -1

@jjy2023 正确答案:
#include<bits/stdc++.h>
using namespace std;
struct RAINBOW{
void AC(){
int a,b;
cin>>a>>b;
cout<<a+b;
}
void WA(){
puts("QWQ");
}
void RE(){
cout << (*(int *)NULL) << endl;
}
void TLE(){
while(1);
}
long long *magic[10086];
void MLE(){
for(int i = 0;;){
magic[i] = new long long;
}
}
void OLE(){
for(long long i = 1;true; i++)
putchar(i % 26 + 'A');
}
void UKE(){
puts("zhang_kevin AK IOI");
}
}Rainbow;
int main(){
int n;
n=rand()%6;
if(n == 1) Rainbow.AC();
if(n == 2) Rainbow.WA();
if(n == 3) Rainbow.RE();
if(n == 4)Rainbow.TLE();
if(n == 5)Rainbow.MLE();
if(n == 6)Rainbow.OLE();
if(n == 7)Rainbow.UKE();
return 0;
}

答案
#include<bits/stdc++.h>
using namespace std;
int main(){
int a,b;
cin>>a>>b;
cout<<a+b;
return 0;
}

@WWW_bilibili_com 开long long
更安全吧,用printf
和scanf
更快吧(要用lld)
by Gcc_Gdb_7_8_1 @ 2023-08-08 15:05:40
@Diandian07go
这个有必要用scanf()
和printf()
吗?
by zouzouzi @ 2023-08-08 15:14:25
@wenlida 这样更快
by Gcc_Gdb_7_8_1 @ 2023-08-08 15:38:44
@Diandian07go
这样是更快,但还会MLE,代码不是TLE或WA,还有,我想问一下,作者为什么要用dfs?
by zouzouzi @ 2023-08-08 15:47:32
@wenlida 我说的是这个代码
#include<bits/stdc++.h>
using namespace std;
int main(){
int a,b;
cin>>a>>b;
cout<<a+b;
return 0;
}
