Time Complexity: O(N) Auxiliary Space: O(1) Efficient Approach: The given problem can be solved based on the following observations: To make the bitwise AND of sequence including N equal to 0, it is necessary to make the MSB bit of the number N equal to 0.; Therefore, the idea is to include all the integers greater than or equal to (2 …
Detect if a number is power of 2 using bitwise operators
WebApproach 4. The idea is to set all bits on the right-hand side of the most significant set bit to 1 and then drop all but the last set bit from n so that it becomes equal to the previous power of two. For instance, consider number 20. We convert its binary representation 00010100 to 00011111. Then drop all set bits except the last one to become ...

WebApr 2, 2024 · For a number that is not a power of 2, applying the AND operator to the number and the number from which we subtract 1 will always result in a value different … WebBitwise OR operator The output of bitwise OR is 1 if at least one corresponding bit of two operands is 1. It is denoted by . Bitwise XOR (exclusive OR) operator ^ The result of bitwise XOR operator is 1 if the corresponding bits of two operands are opposite. It is denoted by ⊕ . For example, for integers 3 and 5, WebJun 27, 2009 · There are other ways to do this:- if a number is a power of 2, only 1 bit will be set in the binary format. for example 8 is equivalent to 0x1000, substracting 1 from this, we get 0x0111. End operation with the original number (0x1000) gives 0. if that is the case, … danbury wisconsin lake homes for sale
