    914 - X of a Kind in a Deck of Cards.

    Easy

    You are given an integer array deck where deck[i] represents the number written on the <code>i<sup>th</sup></code> card.

    Partition the cards into one or more groups such that:

    • Each group has exactly x cards where x &gt; 1, and

    • All the cards in one group have the same integer written on them.

    Return true if such partition is possible, or false otherwise.

    Example 1:

    Input: deck = 1,2,3,4,4,3,2,1

    Output: true

    Explanation:: Possible partition 1,1,2,2,3,3,4,4.

    Example 2:

    Input: deck = 1,1,1,2,2,2,3,3

    Output: false

    Explanation:: No possible partition.

    Constraints:

    • <code>1 <= deck.length <= 10<sup>4</sup></code>

    • <code>0 <= decki< 10<sup>4</sup></code>
