13#include<stdio.h>#include<string.h>int main(){    int i,j,s,flag,num;    char digit[111];    while(~scanf("%s",digit))    {        num=0;        scanf("%d",&s);        if(s>=strlen(digit)) printf("0/n");        else        {            for(i=0;i<s;i++)            {                for(j=0;j<strlen(digit);j++)                {                    if(digit[j]<=digit[j+1]) continue;                    else                    {                        flag=j;break;                    }                }                for(j=flag;j<strlen(digit);j++)                    digit[j]=digit[j+1];            }            for(i=0;i<strlen(digit);i++)            {                if(digit[i]=='0') num++;            }             if(num==strlen(digit)) printf("0/n");             else             {                  for(i=0;i<strlen(digit);i++)                  {                      if(digit[i]=='0') continue;                      else                      {                          flag=i;break;                      }                  }                  for(i=flag;i<strlen(digit);i++)                  {                      printf("%c",digit[i]);                  }                  printf("/n");             }        }    }    return 0;}或者用while.原理是相同的。 #include<stdio.h>#include<string.h>int main(){    int i,s,len,n;    char a[100];    while(~scanf("%s",a))    {        n=0;        scanf("%d",&s);    while(s>0)    {        i=0;len=strlen(a);        while(i<len&&a[i]<=a[i+1])            i++;        while(i<len)        {            a[i]=a[i+1];            i++;        }        s--;    }    len=strlen(a);    while(a[n]=='0'&&n<len) n++;    if(n==len) printf("0/n");    else    {        for(i=n;i<strlen(a);i++)        printf("%c",a[i]);        printf("/n");    }    }    return 0;}
