- c - What is bit masking? - Stack Overflow
In essence, Bitmask is a list of boolean flags (for example isAlive, isMoving, etc) compressed into a single field, usually an integer It can cut quite a significant amount of JSON string size or memory footprint This can be significant especially in PHP where a single boolean in an array can take the same amount of RAM as an integer
- What is Bitmasking - GeeksforGeeks
Bitmask in C++ In the world of programming, where precision and efficiency are of great importance, bitmasking is a powerful technique that utilizes the manipulation of bits C++ also offers a platform where programmers can efficiently represent data and unlock unparalleled computational capabilities through bit m
- Mask (computing) - Wikipedia
In computer science, a mask or bitmask is data that is used for bitwise operations, particularly in a bit field Using a mask, multiple bits in a byte, nibble, word, etc can be set either on or off, or inverted from on to off (or vice versa) in a single bitwise operation An additional use of masking involves predication in vector processing, where the bitmask is used to select which element
- BITMASKS — FOR BEGINNERS - Codeforces
The bitmask to represent this in binary is 01101 or 13 in decimal (in the notes, the 1 st bit will always be the least significant bit and will always appear at the very right) #### MANIPULATING BITMASKS 1 REPRESENTATION: A 32 (or 64)-bit signed integer for up to 32 (or 64) items ( To avoid issues with the two’s complement representation
- Comprehensive Guide to Bit Manipulation and Bitmasking . . . - Medium
A bitmask is a binary number used to control or manipulate individual bits in another binary number Think of it as a set of flags, where each bit serves as a switch that can be turned on (1) or
- Understanding Bitmask for the Coding Interview
Bitmask is the idea of using the binary representation of numbers to solve otherwise difficult problems This representation is unique for each number Example: The bits of the number 11 is "1011", because in base 2: 11 = 8 + 2 + 1 = 12³ + 02² + 12¹ + 12⁰= "1011" When dealing with bitmask: It does not matter what the actual number is

Bitmasks Bit masking is simply the process of storing data truly as bits, as opposed to storing it as chars ints floats It is incredibly useful for storing certain types of data compactly and efficiently
- Bitmask (Bit Manipulation) - VisuAlgo
Bitmask provide an efficient way to manipulate a small set of Booleans that is stored as a 32-(or 64-)bit signed integer in base-10 but interpreted as a short 32-(or 64-) characters string By using bitwise operations, each bit of the integer can be checked, turned on (or turned off) easily and quickly It can be used in various algorithms such as the Dynamic Programming solution for Travelling
