You are given an integer array cards where cards[i] represents the value of the ith card. A pair of cards are matching if the cards have the same value.

\n\n

Return the minimum number of consecutive cards you have to pick up to have a pair of matching cards among the picked cards. If it is impossible to have matching cards, return -1.

\n\n

 

\n

Example 1:

\n\n
\nInput: cards = [3,4,2,3,4,7]\nOutput: 4\nExplanation: We can pick up the cards [3,4,2,3] which contain a matching pair of cards with value 3. Note that picking up the cards [4,2,3,4] is also optimal.\n
\n\n

Example 2:

\n\n
\nInput: cards = [1,0,5,3]\nOutput: -1\nExplanation: There is no way to pick up a set of consecutive cards that contain a pair of matching cards.\n
