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];}
