# [Solution] Minimum Consecutive Cards to Pick Up solution leetcode

Minimum Consecutive Cards to Pick Up solution leetcode – 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.

## [Solution] Minimum Consecutive Cards to Pick Up solution leetcode

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.
```

## [Solution] Minimum Consecutive Cards to Pick Up solution leetcode

```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.
```

## Minimum Consecutive Cards to Pick Up solution leetcode

• `1 <= cards.length <= 105`
• `0 <= cards[i] <= 106`
