有一个点是你2层循环都用的i

破案了......getline的锅，改成cin就过了
另外还有一个地方要注意，你的res要赋初值，不然容易挂（当然这里没挂
```cpp
#include <stdio.h>
#include <iostream>
#include <string>
#include <map>
#include <cstring>
using namespace std;
bool dp[105][105];
int ans_[105][105];
map<string,bool> word;
map<string , string > getwor;
string password;
int cti(char c)
{
if('a' <= c && c <= 'c') return 1;
if(c <= 'f') return 2;
if(c <= 'i') return 3;
if(c <= 'l') return 4;
if(c <= 'n') return 5;
if(c <= 'q') return 6;
if(c <= 't') return 7;
if(c <= 'w') return 8;
if(c <= 'z') return 9;
return -1;
}
char itcn(int num)
{
return (char)(num + 48);
}
inline string getstr(string x,int l,int r)
{
string res;
for(int i = l;i<=r;++i)
{
res += x[i];
}
return res;
}
bool flag = false;
void print(int l,int r)
{
if(ans_[l][r] == -1)
{
if(flag) cout<<" ";
flag = true;
cout<<getwor[getstr(password,l,r)];
}
else
{
print(l,ans_[l][r]);
print(ans_[l][r]+1,r);
}
return ;
}
int main()
{
memset(dp,0,sizeof(dp));
memset(ans_,0,sizeof(ans_));
int n;
scanf("%d",&n);
cin>>password;
int length = password.length();
for(int i=1;i<=n;++i)
{
string worder,old_;
cin>>worder;
int len = worder.length();
old_ = worder;
for(int j=0;j<len;++j)
{
worder[j] = itcn(cti(worder[j]));
}
word[worder] = true;
getwor[worder] = old_;
}
for(int len = 1;len <= length;++len)
{
for(int i=0,j=i+len - 1;j < length;++i,++j)
{
if(word[getstr(password,i,j)] == true)
{
dp[i][j] = true;
ans_[i][j] = -1;
continue;
}
for(int mid = i;mid < j;++mid)
{
if(dp[i][mid] && dp[mid+1][j])
{
dp[i][j] = true;
ans_[i][j] = mid;
break;
}
}
}
}
if(!dp[0][length-1]) printf("No Solutions!");
else print(0,length-1);
// printf("%d",dp[0][length-2]);
return 0;
}

@[Struct_Sec](/user/528908) orz 谢谢巨佬！！！

@[Struct_Sec](/user/528908) 但是，你是怎么发现getline有问题的？（我还没有碰到过STL里除这种问题的）
