N is power of 2

Webb12 apr. 2024 · Given :- ‘N’ = 218 Then the answer will be true because it can be rearranged to 128, which is 2 raised to the power of 7. Input Format : The first line of input contains an integer ‘T’ denoting the number of test cases. The next ‘T’ lines of the test case contain exactly one integer, ‘N’ the number given to us. Output Format : WebbThe n & (n - 1) trick (see Remove rightmost set bit) is also useful to determine if an integer is a power of 2: bool power_of_2 = n && ! (n & (n - 1)); Note that without the first part of the check ( n && ), 0 is incorrectly considered a power of 2. PDF - Download C++ for free. Previous Next.

Webb11 okt. 2024 · Suppose we have a number n. We have to check whether this is power of 2 or not. So, if the input is like n = 2048, then the output will be True as 2048 is 2^11. To solve this, we will follow these steps −. if n is same as 0, then. return False. return true when (n AND (n - 1)) is same as 0 otherwise false.
