WebApr 7, 2024 · There are 41 two-digit numbers where bitwise AND results in 0. All the two-digit numbers will lie in the range [10,99] and for each of them check if the AND of the adjacent digits is equal to 0. Like, say for 10, there are 2 digits 1 and 0, if we do 1&0 this returns 0, so 10 is a valid number. For a number say 25, the digits are 2 and 5.
