2260 - Minimum Consecutive Cards to Pick Up.
Medium
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.
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
