题目 //好一道水水题,可是我居然也错了那么多次,后来百度来发现是因为数据数位可能很长很长,要用字符串数组... //简单 //有坑啊——数据可能很大很大,要用字符串表示! #include<stdio.h> #include<string.h> #include<algorithm> using namespace std; int main() { ]; while(scanf("%s",s)!=EOF) { )break; //无论如何,加一遍…

原题链接 题目大意:给一个数字,每一位相加求和,不断重复过程,直到剩一位数字. 解法:考虑到输入的数字可以很大,把输入按照字符串格式读入,再逐位处理. 参考代码: #include <iostream> #include <string> using namespace std; int main(){ string str; int sum,sum2,i; while(cin>>str&&str!="0"){ sum=0; for(…

水题记录: 注:此题题目并没有限定数值的大小,所以要用字符串进行处理 #include <stdio.h> #include <string.h> int main() { ]; ")) { int len=strlen(n); ; ;i<len;i++) sum+=n[i]-'; ) printf("%d\n",sum); else { ) { ; while(sum) { tmp+=sum%; sum/=; } sum=tmp; } prin…
