Leetcode 154. Find Minimum in Rotated Sorted Array II

Follow up for "Find Minimum in Rotated Sorted Array":
What if duplicates are allowed?

Would this affect the run-time complexity? How and why?

Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand.

(i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2).

Find the minimum element.

The array may contain duplicates.
该题比上题存在重复数字，所以另加一项处理，当遇到重复时候，忽略该值，然后接着使用上题的逻辑处理。代码如下。

int find(int *nums,int s,int t)
{
    if(s==t)
        return nums[s];
    if(nums[s]==nums[t])
    {
        return find(nums,s+1,t);
    }
    if(nums[s]nums[t])min=nums[t];
        return min;
    }
    int mid=(s+t)/2;
    if(nums[mid]>nums[t])
        return find(nums,mid,t);
    return find(nums,s,mid);
}
int findMin(int* nums, int numsSize) {
    int ans= find(nums,0,numsSize-1);
   // printf("%d\n",ans);
    return ans;
}
