上面两句话看不懂

by Sator1 @ 2022-08-17 16:57:46

(3)：把所有两位数组合在一起，写成一个数字，去除前导零，就是去掉数字前面多余的0

(4)：(3)里面有多种组合方式，答案要求组合后的数字最小

by Sator1 @ 2022-08-17 17:00:10

比如(3)中有3个数字 01 12 34

(3)可以组合成011234去除前导0变成11234

也可以组合120134,123401等等

@Sean_xzx

1. 不能有前导零。
2. 要求最后的结果是最小的（答案不是唯一的，所以要求最优解）。

@BCNT 这个题解26~31行什么意思

#include<iostream>

"another","first","second","third"}; 
int sz[30]={0,1,4,9,16,25,36,49,64,81,0,21,44,69,96,25,56,89,24,61,0,
1,4,1,1,4,9};
int k;
int a[10];

int main()
{
    for(int i=1;i<=6;i++)
    {
        string x;
        cin>>x;//直接用变量读就行了
        for(int j=1;j<=26;j++)//26种英文数字
            if(yw[j]==x)
                {a[++k]=sz[j];break;}//k记录有几个英文数字
    }
    if(k==0){cout<<0<<endl;return 0;}//先判断一下句子中有没有英文数字
    sort(a+1,a+k+1);//排序//26
    for(int i=1;i<=k;i++)
    {
        if(i!=1&&a[i]<10)cout<<0;//补0
        cout<<a[i];
    }//31
    cout<<endl;
    return 0;
}

@BCNT 没太懂例题里的答案25 和4 的话254不是更小吗。为什么是425

by zzh25951853 @ 2022-12-02 15:53:49

@b1acat 按照题里的意思是25和04排列，那就应该是2504>0425,而不是254
