簡單題目:1385. Find the Distance Value Between Two Arrays

解: 暴力解

固定任何元素在arr1

之後iterate arr2

class Solution(object):
    def findTheDistanceValue(self, arr1, arr2, d):
        """
        :type arr1: List[int]
        :type arr2: List[int]
        :type d: int
        :rtype: int
        """
       
        count=0
        for i in arr1:
            s=True
            for j in arr2:
                if abs(i-j)<=d:
                    s=False
                    break
            if s:
                count+=1
              
        return count
