On a piano, a key has a frequency, say f$0.$ Each higher key $($black or white$)$ has a frequency of f$0*$ rn$,$ where n is the distance $($number of keys$)$ from that key, and r is $2(1/12).$ Given an initial key frequency $($an integer$),$ output that frequency and the next $4$ higher key frequencies.

Output each floating$-$point value with two digits after the decimal point, which can be achieved as follows:

printf$("\%0\mathrm{.}2$lf$",$ yourValue$)$;

Ex: If the input is:
