题目链接 https://www.patest.cn/contests/pat-a-practise/1065 思路 因为 a 和 b 都是 在 long long 范围内的 但是 a + b 可能会溢出 long long 但是 不会溢出 long double 所以 用long double 就能轻松解决了 或者 用大数加法 也行 AC代码 #include <cstdio> #include <cstring> #include <ctype.h> #includ…

第一眼以为是大数据,想套个大数据模板,后来发现不需要.因为A.B.C的大小为[-2^63, 2^63],用long long 存储他们的值和sum. 接下来就是分类讨论:如果A > 0, B < 0 或者 A < 0, B > 0,sum不会溢出,直接和C判断比较即可.如果A > 0, B > 0,sum可能会溢出, 溢出的话为负数,所以sum < 0时候说明溢出了,那么肯定是大于C的.如果A < 0, B < 0,sum可能会溢出,同理,sum &g…

这次的题目来源是 2013 年 10 月 7 日下午的浙大计算机研究生招生机试题. 这次题目的难度,按姥姥的说法是:『比普通的 PAT 要难了 0.5 个点.我是把自己的题目从 1.0 到 5.0 以 0.5 的间距分难度级别的,PAT(A)难度一般在 1.5-4.5 之间,保研考试一般在 2.0-5.0 之间.PAT(B)大概是 1.0-2.5 的难度.』. 个人认为,其中 1066 模拟 AVL 插入的实现有些细节容易弄错,而 1068 只要会简单的 DP,也就没有问题了,1065 和 10…

1001 A+B Format (20) 输入:两个数a,b,-1000000 <= a, b <= 1000000 输出:a+b,并以每3个用逗号隔开的形式展示. 思路一: 1)计算出a+b的值,赋给sum.判断sum<0,则先输出一个“”-”号,并将sum=-sum(转换为正值):判断sum==0时,则输出0: 2)然后将sum存到一个数组num[10]中,将sum数值的低位存到数组的低位(个位存在数组第1位),用一个while循环:num[i]=sum%10,sum=sum/10;…
