Again, WebFunction bitMask(highbit,lowbit) returns a mask that is 1 between lowbit and highbit, inclusive, and is 0 elsewhere. You may assume that lowbit and highbit are both greater than or equal to 0 and less than or equal to 31. If lowbit > highbit, then the returned mask should be all zero.

WebAug 29, 2024 · A mask defines which bits you want to keep, and which bits you want to clear. Masking is the act of applying a mask to a value. This is accomplished by doing: Below is an example of extracting a subset of the bits in the value: Applying the mask to the value means that we want to clear the first (higher) 4 bits, and keep the last (lower) 4 bits.
