You are given an integer array nums.

\n\n

Return an integer that is the maximum distance between the indices of two (not necessarily different) prime numbers in nums.

\n\n

 

\n

Example 1:

\n\n
\n

Input: nums = [4,2,9,5,3]

\n\n

Output: 3

\n\n

Explanation: nums[1], nums[3], and nums[4] are prime. So the answer is |4 - 1| = 3.

\n
\n\n

Example 2:

\n\n
\n

Input: nums = [4,8,2,8]

\n\n

Output: 0

\n\n

Explanation: nums[2] is prime. Because there is just one prime number, the answer is |2 - 2| = 0.

给你一个整数数组 nums

\n\n

返回两个(不一定不同的)质数在 nums 中 下标最大距离

\n\n

 

\n\n

示例 1:

\n\n
\n

输入: nums = [4,2,9,5,3]

\n\n

输出: 3

\n\n

解释: nums[1]nums[3]nums[4] 是质数。因此答案是 |4 - 1| = 3

\n
\n\n

示例 2:

\n\n
\n

输入: nums = [4,8,2,8]

\n\n

输出: 0

\n\n

解释: nums[2] 是质数。因为只有一个质数,所以答案是 |2 - 2| = 0

\n
\n\n
