<p>Alternatively, and one char shorter:</p> <pre class='brush: python'>checkio=c=lambda a,b,m=1:a and b and((a|b)%2+c(a,b/2,0))*2+(m and c(a/2,b)) </pre> <p>Or without extra parameter:</p> <pre class='brush: python'>checkio=c=lambda a,b:a and b and((-a|b)%2+c(-abs(a),b/2))*2+(a>0and c(a/2,b)) </pre>
