bit_manipulation.is_even.is_even(number: int) → bool

return true if the input integer is even Explanation: Lets take a look at the following decimal to binary conversions 2 => 10 14 => 1110 100 => 1100100 3 => 11 13 => 1101 101 => 1100101 from the above examples we can observe that for all the odd integers there is always 1 set bit at the end also, 1 in binary can be represented as 001, 00001, or 0000001 so for any odd integer n => n&1 is always equals 1 else the integer is even
