WebAll data is stored in its binary representation. The logical operators, and C language, use 1 to represent true and 0 to represent false. The logical operators compare bits in two numbers and return true or false, 1 or 0, for each bit compared. Bitwise AND operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1. WebLet's learn bitwise operations that are useful in Competitive Programming. Prerequisite is knowing the binary system. For example, the following must be clear for you already. 13 = 1 ⋅ 8 + 1 ⋅ 4 + 0 ⋅ 2 + 1 ⋅ 1 = 1101 ( 2) = 00001101 ( 2) Keep in mind that we can pad a number with leading zeros to get the length equal to the size of our ...
