For this task, please submit only the twoDigitString function, whose shell is as follows:

$/**$

$*$ Formats a number as $2$ digits, with a leading $0$ if needed

$*$

$*$ @param n number to format, assumed between $0$ and $59,$ inclusive

$*$ @return two digit string representation of number

$*/$

string twoDigitString$($unsigned int n$)$

To implement this method, you should:

Check if the number is between $0$ and $9.$ If it is$,$ tack a $"0"$ onto the front of the string representation of the number.

Convert the number to a string using your programming language's built$-$in functions.

Return the resulting string.

Remember that the resulting string should always be $2$ digits long. So$,$ if the input number is $0,$ the output should be $"00".$
