��Re� � @ sF d Z d d l Z d d � Z d d � Z d d � Z d d � Z d S) a Given a list of integers, made up of (hopefully) a small number of long runs of consecutive integers, compute a representation of the form ((start1, end1), (start2, end2) ...). Then answer the question "was x present in the original list?" in time O(log(# runs)). � Nc C s� t | � } g } d } x� t t | � � D]{ } | d t | � k rf | | | | d d k rf q+ | | d | d � } | j t | d | d d � � | } q+ Wt | � S)a Represent a list of integers as a sequence of ranges: ((start_0, end_0), (start_1, end_1), ...), such that the original integers are exactly those x such that start_i <= x < end_i for some i. Ranges are encoded as single integers (start << 32 | end), not as tuples. � r ���r )�sorted�range�len�append� _encode_range�tuple)�list_� sorted_list�ranges� last_write�i� current_range� r ��/builddir/build/BUILDROOT/alt-python35-pip-20.2.4-5.el8.x86_64/opt/alt/python35/lib/python3.5/site-packages/pip/_vendor/idna/intranges.py�intranges_from_list s " r c C s | d >| BS)N� r )�start�endr r r r s r c C s | d ?| d @f S)Nr r l l �� r )�rr r r � _decode_range" s r c C s� t | d � } t j | | � } | d k rg t | | d � \ } } | | k o^ | k n rg d S| t | � k r� t | | � \ } } | | k r� d Sd S)z=Determine if `int_` falls into one of the ranges in `ranges`.r r TF)r �bisect� bisect_leftr r )�int_r �tuple_�pos�left�right�_r r r �intranges_contain& s r )�__doc__r r r r r r r r r �<module> s
