Bitwise nuggets: check if a number is a power of 2
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 … WebA power of two is a number of the form 2n where n is an integer, that is, the result of exponentiation with number two as the base and integer n as the exponent . In a context where only integers are considered, n is restricted to non-negative values, [1] so there are 1, 2, and 2 multiplied by itself a certain number of times.

Power of Two LeetCode 231 Check If Number is Power …
WebThe above logic applies to any k. i.e to check if a number is a power of k, see if log to the base k of the number is an integer or not. Using Bitwise operator: In this case we use the check of power-of-2 to check for power-of-4. A number n is a power is a power of 4 if, either it is zero, or: There is only one bit set in its binary ... WebThe following program is used to check if a given number is the power of 2 using bitwise operator. #include define NUM_BITS_INT (8*sizeof (int)) int power2 (unsigned int x) {int i, count = 0, result/shift_num; for (i = 0; i <= NUM_BITS_INT; i--) {shift_num = x >> i; result = shift_num & 1; if (res = 1) count++;} if (count % 2 == 1) WebRead an integer number, and check whether the input number is a power of 2 or not using bitwise operator.
