Web4 bitwise logical operators: & (Bitwise AND), (Bitwise OR), ^ (Bitwise XOR), and ~ (Bitwise NOT). 3 bitwise shift operators: << (Left shift), >> (Sign-propagating right shift), and >>> (Zero-fill right shift). JavaScript's bitwise operators treat their operands as binary numbers -- sequences of 32 bits -- but return decimal numbers.

The integers are converted into binary format and then operations are performed bit by bit, hence the name bitwise operators. Python bitwise operators work on integers only and the final output is returned in the decimal format. WebA technique they most certainly used is the manipulation of bitfields for some data structures because they are light and fast, especially much lighter in terms of memory and processing than the Python dictionaries and lists. They are not adapted for every use though: they are limited, trickier to get right, and not super easy to debug. how to research paper steps reddit
