    The "i don't type for free way"-

    return sum(v // 2 for v in counts.values())

    There are two ways to solve this with Counter: The normal way-

    # result = 0
    # for a in ar.values():
    #     result += int(a/2)
    # return result

    def sockMerchant(n, ar):
    arr=ar
    ans=[]
    arr=list(set(arr))
    for i in arr:
        ans.append(ar.count(i)//2)
    return sum(ans)
