Encode Number
The pattern can be understood as encoding the integer in a manner similar to the binary representation, but without the leading zero bit. It means you can find the encoding string by converting num + 1
to binary and then skipping the leading ‘1’.
Here’s how you can implement this:


The bin
function will convert num + 1
to a binary string, and [3:]
will slice the string to skip the first three characters (‘0b’ and the leading ‘1’). This will give you the encoding for the given integer.
