A Beginners Guide to Bit Manipulation |
https://dev.to/theinsightfulcoder/a-beginners-guide-to-bit-manipulation-35ek
|
A Beginners Guide to Bit ManipulationBit Manipulation or Bit Magic as it is popularly known as is a technique where we work directly on binary data or bits which results in faster code execution If the concept seems to be frightening don t worry We will bust and understand everything with examples In this article we ll explore Overview of Decimal and Binary Number System a Conversion of Decimal number system gt Binary Number System Conversion of Binary number system gt Decimal Number System b Addition and Subtraction of Binary numbers Bitwise operators Significance of these operations a General Application b Swapping c Even and Odd Overview of Decimal and Binary Number SystemThe most common convention of writing numbers is the decimal number system In this system we write numbers in the power of For example x x x Similarly computers are habituated to work on Binary numbers corresponding to base x x x a Conversion of Decimal number system gt Binary Number System and vice versai Decimal number system gt Binary Number SystemWe convert decimal to binary by division as we are going from base to base gt The trick is to keep dividing the number by and write the remainder beside it remainder remainder remainder You ve to write the binary bits in the bottom up order along with at the front So the binary representation of will come as ii Binary Number System gt Decimal number systemWe convert binary to decimal using multiplication as seen above x x x b Addition and Subtraction of Binary numbers i AdditionThis is the truth table for addition of Binary digits Number Number Sum Carry If we add we get the sum as with no carry we get the sum as and no carry we get the sum as and no carry we get the sum as and the carry as Let s say we want to perform addition as The computer converts and from the decimal number system to the binary number system Adding the binary representation according to the truth table The highlighted represents the carry bit Convert to decimal we get the result as that is in fact ii SubtractionSpoiler alert There s nothing known as subtraction in the computer The computer uses a method called s complement to perform subtraction using addition So if we want to perform the computer treats it as Step Convert numbers from the decimal number system to the binary number system Step Invert the bits of the number to be subtracted Change to and to Step Add the numbersIf a carry is generated from the most significant bit MSB ーthe leftmost bit that means the result is positive Discard the carry it and add to obtain the final answer If no carry is generated that means the number is negative In this case you ve to invert the bits of the answer Step Convert the answer obtained in binary back to the decimal number system Therefore we get the answer as Bitwise operatorsAs we have Arithmetic operators to work on Decimal numbers we have Bitwise Operators to work on Binary Numbers The most commonly used Bitwise operators are Bitwise AND amp Bitwise OR Bitwise XOR Bitwise NOT Right Shift gt gt Left Shift lt lt Number Number AND amp OR XOR Consider this as the master table How to build this table AND amp If both the bits of the numbers are the output is else OR If both the bits of the numbers are the output is else XOR If both the bits of the numbers are different the output is else Let s explore the other operators NOT works on single bits It inverts the value of the bits If the input is it converts it to and vice versa Right Shift gt gt Shifts the position of bits to one place towards the right The significance of the right bit is that it divides the number by For example let s say we have to right shift the number two times Problem gt gt Solution becomes in Binary Right shift bits once Right shift bits twice Hence gets converted to and then Left shift lt lt Shifts the position of bits to one place towards the left The significance of the left bit is that it multiplies the number by For example let s say we have to left shift the number two times Problem lt lt Solution becomes in Binary Right shift bits once Right shift bits twice Hence gets converted to and then Significance of these operations a General ApplicationLet s say you wanted to write a code where you are constantly multiplying dividing the term by for int i i lt N i i Instead of multiplication you can directly use the left shift operator in the updation phase for int i i lt N i i lt lt b SwappingYou can perform swapping without the need for a third variable The magic is created by the XOR operator int a b a b b a a b c Even OddWhat if I told you that we can completely eliminate the use of the modulo operation to find out whether a number is even or odd We can achieve this using Bit Masking Before diving into Bit Masking I would like to perform a small quiz What is the pattern among these numbers If you notice correctly you d observe that the last digit of each even number is Similarly for odd numbers the last digit is Therefore to distinguish between even and odd numbers we just need to figure out whether the last digit of a number is The concept is if we use AND any number with we would receive the last digit of the number For example i amp ii amp We can simply compare the result with and verify if our number is even or odd This process is called Bit Masking We use as a mask and perform an operation to get the desired output Code snippet for Even and Odd numbers using Bit Manipulation technique int i if i amp System out println Even Number elseSystem out println Odd Number That s it for today folks In the next part of this series we would discuss Bit Masking Techniques and move on to explore some advanced Bit Manipulation Techniques amp Algorithms This article was inspired by the DSA

Supercharge your API with Compression |
https://dev.to/mikeeason/supercharge-your-api-with-compression-4ikp
|
Supercharge your API with CompressionPerformance is critical to any API taking the time to reduce API response times to be as low as possible is absolutely worth the effort Take a look at this example API request in Solaris The API response is kB with a time of ms This isn t terrible but could be smaller and faster with compression Express CompressionIf you re familiar with Node js you have probably used Express js at some time or another Express is extensible and has a large number of middleware libraries that can be bolted on One such library is compression To install compression npm install compressionThen its a case of simply calling the Express use function to register the middleware like this const express require express const compression require compression const app express Compress all responsesapp use compression threshold Byte threshold means compress everything Easy right Now calling the same API endpoint we get this The response is now kB and a time of ms that s over x faster than before Compressing Specific ResponsesWith the above code we ll be compressing all responses if for some reason you d like to not compress a response from the API then we can override the filter function like this app use compression threshold filter req res gt if req headers x no compression don t compress responses if this request header is present return false fallback to standard compression return compression filter req res Any API request with the x no compression header will be ignored And that s it your API will now serve compressed responses and should now be performing even better than before In my spare time I develop an open source strategy game called Solaris check it out |
