总结: 1.使用库函数可有效节省空间,但时间花费较多; 2.由于本题的输入数据较大，又限制时间,故要注意利用空间换时间; 3.使用顺序结构换取最小运行时间; 示例代码: #include <stdio.h>#include <string.h>#define N1 100000 /*16进制*/#d 阅读全文

注意事项: 1.长数据注意选择long long类型,用%ldd输出,防止数据溢出; 示例代码: #include <stdio.h>#include <string.h>#include <math.h>#define N 16 int main(void){ char c = 0; char a 阅读全文
