代码

#include <iostream>
#include <cstdio>

#define getchar() (S==T&&(T=(S=BB)+fread(BB,1,1<<15,stdin),S==T)?EOF:*S++)
char BB[1<<15],*S=BB,*T=BB;;

    f = 0;Re char c; 
    while(c=getchar(),c<=47||c>=58);f=(f<<3)+(f<<1)+c-48;
    while(c=getchar(),c>=48&&c<=57) f=(f<<3)+(f<<1)+c-48;
    return f;
}
void write(int x){
    /*在这一行你可以进行一些特殊处理和判断，例如处理负数等*/
    if(x>9) write(x/10);//能分解则分解
    putchar(x%10+48);//利用C++putchar速度快的因素加速输出
}

int main () {
#ifdef _DEBUG
    int tt = clock();
#endif
    
    register int i, j;
    i = read(); j = read();
    write(i + j);

#ifdef _DEBUG
    std::cout << "TIME = " << clock() - tt << endl;
