WebIn computer science, a maskor bitmaskis 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. WebTo achieve this we need to follow two steps firstly we need to flip the bits of the input number and store it in a mask. Thereafter we need to add 1 to the mask to get our desired mask.
