上面两句话看不懂

(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

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

1. 不能有前导零。
1. 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](/user/226919) 这个题解26~31行什么意思
```cpp
#include<iostream>
#include<algorithm>
using namespace std;
string yw[30]={"","one","two","three","four","five","six","seven",
"eight","nine","ten","elven","twelve","thirteen","fourteen","fifteen",
"sixteen","seventeen","eighteen","nineteen","twenty","a","both",
"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](/user/226919) 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 b1acat @ 2022-11-28 21:10:33
@[b1acat](/user/878821) 按照题里的意思是25和04排列，那就应该是2504>0425,而不是254
