我们建两个字符串，在处理第一个字符串的时候，我们先把数字加起来，再把小写转大写。
记得最后把所有大写字母加到后一个字符串里。
再遍历第二个字符串，把元素输出
耗时：1ms
空间：3.40MB
看代码：
#include<iostream>
using namespace std;
int cnt;
string kl,wl;
signed main(){
ios::sync_with_stdio(0);
cin.tie(0),cout.tie(0);
cin>>kl;
for(auto er:kl){
if(er>='0'&&er<='9'){
cnt+=int(er-'0');
}else if(er>='a'&&er<='z'){
er=er-'a'+'A';
}
if(er>='A'&&er<='Z'){
wl+=er;
}
}
cout<<cnt<<endl<<'[';
cnt=wl.size();
for(int i=1;i<=cnt;i++){
cout<<"'"<<wl[i-1]<<"'"<<(i==cnt?"]":", ");
}
return 0;
}
