What is the complexity of this code ?

I was solving a problem that need to find the minimum distance between two points. I tried to bruteforce then cde an divide and conquer algorithm. But then I modified the bruteforce by adding some branch-and-bound to ignore not-optimal cases. For somehow my code get AC and seems to run fast while I thought it will be slow with the complexity of $$$O(n^2)$$$ with small constant.

I dont really sure about the complexity, can some one help me to calculate it ?
