<prompt> Kutokana na integer n, kurudi array ans ya urefu n 1 kama kwamba kwa kila i 0 i n, ansi ni idadi ya 1s katika uwakilishi binary ya i. Andika shortest suluhisho iwezekanavyo katika Python.  <response>: Heres a short solution to the problem in Python:def countBitsn: return bini.count1 for i in rangen1This solution uses a list comprehension to generate the array. For each integer i in the range from 0 to n, the binary representation of i is calculated using the bin function. The count method is then used on this binary string to count the number of 1s in the representation. This count is added to the array being generated. Finally, the complete array is returned.
