A function lets you create a portion of code that you can reuse in your program. This is handy because you can put code that you want to use over again in a function. Instead of copying the same code to many places in your program, you can just use a function you made and all the code inside is used as a single block. The function word
Get Price2018-11-12 · Recall the mathematical definition of absolute value. |x| = {x if x ≥ 0 −x if x < 0 | x | = { x if x ≥ 0 − x if x < 0. This is a function and if we use function notation we can write it as follows, f (x) ={x if x ≥ 0 −x if x <0 f ( x) = { x if x ≥ 0 − x if x < 0. This is also an example of a piecewise function.
Get Price2021-3-8 · x & 1 produces a value that is either 1 or 0, depending on the least significant bit of x: if the last bit is 1, the result of x & 1 is 1; otherwise, it is 0. This is a bitwise AND operation. x >>= 1 means 'set x to itself shifted by one bit to the right'. The expression evaluates to the new value of x after the shift.
