2260 - Minimum Consecutive Cards to Pick Up.
Medium

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

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.

Example 1:

Input: cards = [3,4,2,3,4,7]

Output: 4

Explanation: 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.

Example 2:

Input: cards = [1,0,5,3]

Output: -1

Explanation: There is no way to pick up a set of consecutive cards that contain a pair of matching cards.

Constraints:
- 1 <= cards.length <= 10⁵
- 0 <= cards[i] <= 10⁶
