    Question is worded poorly (says subarray, when it means subset), and the example works either way, so there's no way of catching the misunderstanding without looking at the sample test cases

    from collections import Counter
def pickingNumbers(a):
    # Write your code here
    freq=Counter(sorted(a))
    length_array=[]
    for i in freq:
        print(i,freq[i])
        length_array.append(freq[i]+freq[i+1])
    return max(length_array)

    Hackerrank should clarify their question. Subarray is the wrong word to use. It should be subsequence

    def pickingNumbers(a):
        # Write your code here
        a.sort()
        p = 0

        for s in range(len(a)):
                if a[s] - a[p] > 1:
                        p += 1

        return s - p + 1

    The test cases miss a basic case of '1 2 2 3 3 5'. A lot of answers submitted here give wrong answer for this case (3 instaed of 4).
