WebOct 17, 2024 · 2. A "constant", in computer programming terms, is a value that is known at compile time, based entirely on the program's source code. This value can be the result of some calculation, but the only inputs allowed are other constants. For example, you could define a constant with value 2 * Math.PI. WebAug 18, 2015 · "Constant time" means that the operation will execute in an amount of time (or memory space - that's another thing often measured) independent of the input size. Usually you pick a variable (let's use n) to indicate the input size. O (1) - constant time - running time does not depend on n
