HDU2051 递归 转化为二进制

#include<stdio.h>int change(int a){    if(a/2){    change(a/2);    }    printf("%d",a%2);}int main(){    int m;    while(scanf("%d",&m)!=EOF){        change(m);        printf("\n");        }        return 0;    }递归 可以装逼啊！！！//一般方法#include<stdio.h>int main(){    int s[10];    int m,i,j;    while(scanf("%d",&m)!=EOF){        i=1;    while(m){        s[i]=m%2;        m/=2;        i++;    }    j=i-1;    for(i=j;i>=1;i--)    printf("%d",s[i]);    printf("\n");    }    return 0;}
