WebMar 10, 2013 · How do you like this one: def bitsoncount (x): b = 0 bit = 1 while bit <= x: b += int (x & bit > 0) bit = bit << 1 return b. Basically, you use a test bit that starts right and gets shifted all the way through up to the bit length of your in parameter. For each position the bit & x yields a single bit which is on, or none. WebcountBits = n => n.toString (2).split ('0').join ('').length; 1.Here n.toString (2) converts n into binary string. 2.split ('0') makes array out of the binary string splitting only at 0's and hence returning an array of only 1 present in binary of n. 3.join …
