public string replaceletter(string word, char lettertoreplace, char replacingletter) {     string ans = "";     for(int = 0; < word.length(); i++)     {         char current = word.charat(i);         if(current == lettertoreplace)         {            lettertoreplace = replacingletter;         }         ans += character.tostring(word.charat(i));     }     return ans; }
