On a piano, each key has a frequency, and each subsequent key (black or white) is a known amount higher. ex: the a key above middle c key has a frequency of 440 hz. each subsequent key (black or white) has a frequency of 440 * rn, where n is the number of keys from that a key, and r is 2(1/12). given an initial frequency, output that frequency and the next 3 higher key frequencies. if the input is 440, the output is: 440 493.883 523.251 554.365.note: include one statement to compute r = 2(1/12) using the pow function, then use r in the formula fn = f0 * rn. (you'll have three statements using that formula, different only in the value for 4/17/17: a student noticed that our example and test cases are skipping n=1, starting instead with n=2. we won't change the lab right now, so just assume you've been asked for steps n=2, 3, and 4.)

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.
