  • 看个人思路吧,清晰的话就简单 CodeForces 271A

    It seems like the year of 2013 came only yesterday. Do you know a curious fact? The year of 2013 is the first year after the old 1987 with only distinct digits.

    Now you are suggested to solve the following problem: given a year number, find the minimum year number which is strictly larger than the given one and has only distinct digits.

    Input

    The single line contains integer y (1000 ≤ y ≤ 9000) — the year number.

    Output

    Print a single integer — the minimum year number that is strictly larger than y and all it's digits are distinct. It is guaranteed that the answer exists.

    Sample test(s)
    input
    1987
    
    output
    2013
    
    input
    2013
    
    output
    2014
    
    题意就是说给你一个年份,当然是四位数的,然后要你找出比这个数大且是最先打到四位数每一个数字都不一样,可能有些同志英语不好看不懂然后小弟语文差表述也有问题,这样说吧:2013是给定的数字,比2013大且最先达到每一个数字都不一样就是2014   2    0    1    4;如今应该能明确了吧?
    那咱们如今就来讲讲思路:
    定义一个year作为输入,然后就是while(1)的一个循环,再定义一个flag作为标记,初值为0;
    然后就是取各个数位上的数字分别赋值给a,b,c,d,然后就是一个if比較,假设不一样则flag=1;
    然后推断flag是否为一,为一代表已找到符合条件的数字,则break;
    这里有一点注意的是:输入year之后一定要加一,不然像2013这种是会输出2013滴!!!!!!切记,好啦,讲完!!!!!!
    贴下代码:
    #include<stdio.h>
    #include<string.h>
    #include<iostream>
    using namespace std;
    int main()
    {
        int i,j,k;
        int t,n,m;
        int a,b,c,d;
        int year,flag;
        while(scanf("%d",&year)!=EOF)
        {
            flag=0;
            //printf("%d %d %d %d
    ",a,b,c,d);
            while(1)
            {
                year++;    //千万注意这里!!!!!!千万千万千千万!!!!!!
                d=year%10;
                c=(year/10)%10;
                b=(year/100)%10;
                a=(year/1000);
                if(a!=b&&a!=c&&a!=d&&b!=c&&b!=d&&c!=d)
                {
                    flag=1;
                }
                if(flag==1)
                    break;
    
            }
            printf("%d
    ",year);
        }
        return 0;
    }

    如有发现bug,就指出来吧!!!!!!不胜感激!!!!!!
