WebIterative approach. Negative numbers and zero can never be in form 2^y where y is an integer. check if n can be divided by 2. If yes, divide n by 2 and check it repeatedly. if at last n is reduced to 1 then n is a power of 2 else it is not the form 2^y where y is an integer.
WebTo write a program to check if an integer is a power of two, you could follow two basic strategies: check the number based on its decimal value, or check it based on its binary representation. The former approach is more human-friendly but generally less efficient; the latter approach is more machine-friendly but generally more efficient.
