超时的快慢指针，可是超时了。。呜呜呜

int singleNonDuplicate(int* nums, int numsSize){
    //快慢指针，如果前一位与当前一位相等，那把fast赋值给slow，进行前移
    int slow=0,fast=1;
    int ans=0;
    int len=numsSize;
    if(len==1)
    {
        return nums[0];
    }
    while(slow 
int singleNonDuplicate(int* nums, int numsSize){
  for(int i=0;i 
int singleNonDuplicate(int* nums, int numsSize){
  int left=0;
  int right=numsSize;
  while(left=0&&nums[mid-1]==nums[mid])
              {
                  left=mid+1;
              }
              else{
                  right=mid;
              }
          }
      
  }
  return nums[right];
}
