The basic task is simple: given N real numbers, you are supposed to calculate their average. But what makes it complicated is that some of the input numbers might not be legal. A legal input is a real number in [−1000,1000] and is accurate up to no m…

The basic task is simple: given N real numbers, you are supposed to calculate their average. But what makes it complicated is that some of the input numbers might not be legal. A legal input is a real number in [−1000,1000] and is accurate up to no m…

题意: 输入一个正整数N(<=100),接着输入一行N组字符串,表示一个数字,如果这个数字大于1000或者小于1000或者小数点后超过两位或者压根不是数字均为非法,计算合法数字的平均数. trick: 测试点2答案错误原因:题面指出如果只有一个合法数字,输出numbers的时候不加s,即为number. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std;…

话不多说: 该题要求将给定的所有数分为两类,其中这两类的个数差距最小,且这两类分别的和差距最大. 可以发现,针对第一个要求,个数差距最小,当给定个数为偶数时,二分即差距为0,最小:若给定个数为奇数时,差距为1时最小. 针对第二个要求:则将所有给定的数从小到大排列,将前半部分给那个和小些的集合,其余给那个和大的集合,这样做和差距会最大. 以此思路编写代码如下: #include<cstdio> #include<iostream> #include<algorithm>…
