B2037奇偶性判断新解法

原题传送门

#include <bits/stdc++.h>
using namespace std;
int main(){
	freopen("C:\\Users\\Tellol_go\\Desktop\\B2037 ANS.txt","w",stdout);
	cout<< "#include <bits/stdc++.h>\nusing namespace std;\nint main(){\n";
	const char ch='"';
	cout<< "    int n;\n    cin>> n;\n";
	for(int i=-100;i<=100;i++){
		if(i%2==0)
			printf("    if(n==%d)\n    cout<< %ceven%c;\n",i,ch,ch);
		else
			printf("    if(n==%d)\n    cout<< %codd%c;\n",i,ch,ch);
	}
	cout<< "}";
}

你猜这玩意干嘛的？

是用来生成暴力破解代码的！
打开桌面文档一看，生成样式如下：

#include <bits/stdc++.h>
using namespace std;
int main(){
    int n;
    cin>> n;
    if(n==-100)
    cout<< "even";
    if(n==-99)
    cout<< "odd";
    if(n==-98)
    cout<< "even";
    if(n==-97)
    cout<< "odd";
    if(n==-96)
    cout<< "even";
    if(n==-95)
    cout<< "odd";
    if(n==-94)
    cout<< "even";
    if(n==-93)
