$2$ Most common character

Write a function that takes an input string and returns the most common character from the string,

and the number of times it appeared. For example, the string $$data$$ could return $($a$,2).$

Note: For some words, there may be multiple $$most common$$ letters. Your function does

not need to return all of them. As long as your function returns one of them it will be

considered correct. For example, in the word $$noon$,$ either $($n$,2)$ or $($o$,2)$ would be

correct.

Milestone $2$:

To get checked off for this portion of the lab, show correct output from the function using

words your TA gives you. For example, if your program contains this code:

System.out.println$($mostCommonChar$("$bejeweled$"))$;

Then your output should be:

$("$e$",4)$
