大数问题(三)(大数相除)
题意:求两个大数相除的商
分析如下:
相应代码如下:
#include<iostream> #include<string> #include<stdio.h> #include<string.h> using namespace std ; int main() { char a[100] ; int b ; while(cin >> a >> b) { int len = strlen(a) ; int sum = 0 , yu_shu = 0 ; for(int i = 0 ; i < len ; i++) { sum = a[i]- '0' + yu_shu * 10 ; int t = sum / b ; // 取商 yu_shu = sum % b ; //取余 if(t != 0) // 如果商不为0,输出商 cout << t ; } } return 0 ; }
JAVA代码实现如下:
import java.math.BigInteger; import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in) ; while(sc.hasNext()) { BigInteger s = new BigInteger(sc.next()) ; BigInteger t = new BigInteger(sc.next()) ; s = s.divide(t) ; System.out.println(s); } } }
