hi @aman17nov1999
(k&1) is used to determine if k is odd or not
if k is odd, then its last bit will be 1 and k & 1 will also be 1 which will result in boolean true
if k is even, then its last bit will be 0 and k & 1 will be 0 which will result in boolean false

Is that what you mean or is it something else?
