while(i < this.puzzleWords.size())

你正在尝试每一个单词。



在你现有的while循环中添加另一个while循环，定义为在找到位置时结束：

you are trying each word once.

add another while loop inside your existing while loop, defined to end when the position is found:

while(i < this.puzzleWords.size()) { // each word

  while(positionNotFound){ //search until...
 
    // your code
    // .....
    //....
    if(positionFound){
      break; //leave inner while
    }
  }

}
