数组中，有一个元素的值在数组中重复的个数是超过一半，获得元素超过一半的元素值

int MoreThanHalfNumber(int * arr, int n){

                 int result = arr [0];

                 int time = 1;

                 for (int i = 1; i < n; i++){

                                 if (time == 0){

                                                result = arr[i];

                                                time = 1;

                                }

                                 else if (arr[i] == result){

                                                time++;

                                }

                                 else{

                                                time--;

                                }

                }

                 return result;

}
