SRM486 Div2 Easy(250) TxMsg - kusano

Div2 250にしては面倒な気がする。

#include <string>
#include <sstream>

using namespace std;

class TxMsg{public:
string getMessage( string original )
{
    bool vowel[256] = { false };
    vowel['a'] = vowel['e'] = vowel['i'] = vowel['o'] = vowel['u'] = true;

    string ans = "";

    stringstream ss(original);
    string word;
    while ( ss >> word )
    {
        string abbr = "";
        for ( int i=0; i<(int)word.length(); i++ )
            if ( ! vowel[word[i]]  &&  ( i == 0  ||  vowel[word[i-1]] ) )
                abbr += word[i];

        ans += " " + ( abbr!="" ? abbr : word );
    }

    return ans.substr(1);
}};
