WebNov 10, 2024 · Write a Java program to check whether an given integer is power of 2 or not using O (1) time. Note: O (1) means that it takes a constant time, like 12 nanoseconds, or two minutes no matter the amount of data in the set. O (n) means it takes an amount of time linear with the size of the set, so a set twice the size will take twice the time.
