I'm doing a job where I have to do some calculations with batteries and I need to do tests for two powers and two powers plus two, ie 1, 2, 3, 5, 8, 9, 16, 17 , etc.
The power part of two is done easily, but how do I loop or cycle the powers of two plus one?
It's simple, just do the power calculation and then add 1.
As no more details follow below. The code calculates all powers of 2 and powers of 2 with 1.
Scanner input = new Scanner(System.in);
System.out.print("Digite um número: ");
int numeroEscolhido = input.nextInt(); //número digitado pelo usuário
for(int i = 0; i <= numeroEscolhido; i++){
int potenciaDe2 = (int)Math.pow(2, i);
int potenciaDe2Mais1 = (int)Math.pow(2, i) + 1;
System.out.println(String.format("(2^%s): %s | (2^%s)+1: %s", i, potenciaDe2, i, potenciaDe2Mais1));
}
Entering the number 5 , the output will be:
(2^0): 1 | (2^0)+1: 2 (2^1): 2 | (2^1)+1: 3 (2^2): 4 | (2^2)+1: 5 (2^3): 8 | (2^3)+1: 9 (2^4): 16 | (2^4)+1: 17 (2^5): 32 | (2^5)+1: 33
