Given a non-empty array of non-negative integers nums, the degree of this array is defined as the maximum frequency of any one of its elements.

\n\n

Your task is to find the smallest possible length of a (contiguous) subarray of nums, that has the same degree as nums.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [1,2,2,3,1]\nOutput: 2\nExplanation: \nThe input array has a degree of 2 because both elements 1 and 2 appear twice.\nOf the subarrays that have the same degree:\n[1, 2, 2, 3, 1], [1, 2, 2, 3], [2, 2, 3, 1], [1, 2, 2], [2, 2, 3], [2, 2]\nThe shortest length is 2. So return 2.\n
\n\n

Example 2:

\n\n
\nInput: nums = [1,2,2,3,1,4,2]\nOutput: 6\nExplanation: \nThe degree is 3 because the element 2 is repeated 3 times.\nSo [2,2,3,1,4,2] is the shortest subarray, therefore returning 6.\n
