trailing_ones
trailing_ones(x::Integer) -> Integer
Number of ones trailing the binary representation of x.
julia> trailing_ones(3)
2Examples
-
Count trailing ones in a binary number:
julia> trailing_ones(3) 2This example counts the number of ones trailing the binary representation of the number
3. -
Find trailing ones in a larger binary number:
julia> trailing_ones(100) 0It returns the count of trailing ones in the binary representation of the number
100. - Handle zero as input:
julia> trailing_ones(0) 0When the input number is zero, it correctly returns zero as there are no trailing ones.
Common mistake example:
julia> trailing_ones(7.5)
ERROR: MethodError: no method matching trailing_ones(::Float64)
In this example, the input to the trailing_ones function is a floating-point number. It's important to note that trailing_ones only accepts integers as the input. Ensure that the input is of the correct type to avoid such errors.
