题目链接: B. Barnicle 题意:给出科学计数法 转化成十进制的整数或小数 并输出. 思路:暑假训练赛见过了,当时大腿A掉了,并表示是道水题. 刷CF再次遇见,毫不留情WA了几次.比如: 0.e0       0 1.0e0     1 突然觉得自己不能再依赖CF这种看着sample dbug的模式了. 附代码: /// 给出科学计数法 转化成十进制的整数或小数 并输出 #include <stdio.h> #include <string.h> #include <…

对科学计数法表示的数,输出其10进制的形式. c++来做,需要考虑这些细节: 当b==0,d==0时,只输出a. 当不需要补零的情况有两种: 一种是刚好是整数,只输出a(注意1.0e1的情况是输出1):另一种是还要输出剩下的小数部分. #include<cstdio> #include<algorithm> #define N 200005 using namespace std; int a,b,dl,dr; char s[N]; int main(){ scanf("…

题目链接:http://codeforces.com/problemset/problem/697/B 题目大意: 将科学计数法用十进制表示.[如果类似于7.0应输出7] 解题思路: Java 中 BigDecimal 类型可以直接对其转,注意输出. AC Code: import java.math.BigDecimal; import java.util.Scanner; public class Main { public static void main(String[] args) {…
