1. Description

Maximum Distance Between a Pair of Values

2. Solution

解析:Version 1,由于两个数组都是非增数组,因此保证了数值的大小关系,如果i<=j,此时比较nums1[i] <= nums2[j],如果符合,则计算距离distance,并与已有距离比较取较大值,在i<=jnums1[i] > nums2[j]的情况下,此时应该移动i,如果i>j,则移动j,由于保证了大小关系,因此只要遍历完一个数组即可。Version 2是对Version 1的进一步优化。

  • Version 1
class Solution:
    def maxDistance(self, nums1: List[int], nums2: List[int]) -> int:
        distance = 0
        i = 0
        j = 0
        while i < len(nums1) and j < len(nums2):
            if i <= j:
                if nums1[i] <= nums2[j]:
                    distance = max(distance, j - i)
                    j += 1
                else:
                    i += 1
            else:
                j += 1
        return distance
  • Version 2
class Solution:
    def maxDistance(self, nums1: List[int], nums2: List[int]) -> int:
        distance = 0
        i = 0
        j = 0
        while i < len(nums1) and j < len(nums2):
            if nums1[i] > nums2[j]:
                i += 1
            else:
                distance = max(distance, j - i)
                j += 1
        return distance
