The rule of $\text{'}72\text{'}$ is used to quickly approximate how rapidly an investment, at a fixed interest rate, will double. If you divide $72$ by the interest rate $($as a percent$)$ you will get years. Example an investment earning $10\%$ would double in approximately $7\mathrm{.}2$ years $(72/10).$ Write a program to display the number of years to double an investment at $5\mathrm{.}5\%.$ Place the interest rate in the variable i$,$ your calculation in the variable y$,$ and print the result.
