%S 1,2,3,4,5,6,7,8,9,11,22,33,44,55,66,77,88,99,100,101,110,111,112,113,

%N Numbers in which more than half of the digits are the same.

%C Same as A044959 for terms <= 1000, and then differing at A044959(272) = 1001 which is not a term here (the next instead a(272) = 1011).

%H Zhining Yang, <a href="/A353181/b353181.txt">Table of n, a(n) for n = 1..30000</a>

%e 1211 is a term: it has 4 digits, 3 of which are 1's, and 3/4 > 1/2.

%e 1212 is not a term: it has 4 digits, no one of which appears more than twice.

%t Select[Range[300], Max[DigitCount[#]] > IntegerLength[#]/2 &]

%o (Python)

%o def ok(k):

%o t=str(k)

%o return(max(t.count(str(i)) for i in range(10))>(len(t)//2))

%o print([n for n in range(1, 201) if ok(n)])

%Y Cf. A109303, A044959.

%K nonn,base,easy

%O 1,2
