1060 Are They Equal(25 分) If a machine can save only 3 significant digits, the float numbers 12300 and 12358.9 are considered equal since they are both saved as 0.123×10​5​​ with simple chopping. Now given the number of significant digits on a machin…

题目意思直接,要求将两个数转为科学计数法表示,然后比较是否相同  不过有精度要求 /* test 6 3 0.00 00.00 test 3 3 0.1 0.001 0.001=0.1*10^-2 pay 前导0 不同格式的0 */ #include<iostream> #include<stdio.h> #include<string.h> using namespace std; char a[105],b[105]; struct num { char s[105…

If a machine can save only 3 significant digits, the float numbers 12300 and 12358.9 are considered equal since they are both saved as 0.123*105 with simple chopping. Now given the number of significant digits on a machine and two float numbers, you…

1060 Are They Equal (25分) 题目 思路 定义结构体 struct fraction{ string f; int index; } 把输入的两个数先都转换为科学计数法,统一标准后再做比较,index表示指数 注意点 0或者0的各种形式 0.1, 0.01等 代码 #include<cstdio> #include<cstring> #include<cmath> #include<algorithm> #include<vect…

PAT乙级:1090危险品装箱(25分) 题干 集装箱运输货物时,我们必须特别小心,不能把不相容的货物装在一只箱子里.比如氧化剂绝对不能跟易燃液体同箱,否则很容易造成爆炸. 本题给定一张不相容物品的清单,需要你检查每一张集装箱货品清单,判断它们是否能装在同一只箱子里. 输入格式: 输入第一行给出两个正整数:N (≤104) 是成对的不相容物品的对数:M (≤100) 是集装箱货品清单的单数. 随后数据分两大块给出.第一块有 N 行,每行给出一对不相容的物品.第二块有 M 行,每行给出一箱货物的清…

PAT乙级:1070 结绳 (25分) 题干 给定一段一段的绳子,你需要把它们串成一条绳.每次串连的时候,是把两段绳子对折,再如下图所示套接在一起.这样得到的绳子又被当成是另一段绳子,可以再次对折去跟另一段绳子串连.每次串连后,原来两段绳子的长度就会减半. 给定 N 段绳子的长度,你需要找出它们能串成的绳子的最大长度. 输入格式: 每个输入包含 1 个测试用例.每个测试用例第 1 行给出正整数 N (2≤N≤104):第 2 行给出 N 个正整数,即原始绳段的长度,数字间以空格分隔.所有整数都不…
