#Write a for$-$each loop that lists each character in #mystery$\_$string with its index. For example, if the string #was "David", the output would be: #$0$ D #$1$ a #$2$ v #$3$ i #$4$ d # #Note that the first item is #$0,$ the second is #$1,$ and so #on$!$ We'll talk about why that is in Unit $4.$ # #Hint: You'll need a separate variable to keep track of how #many letters you've printed! You may not use the range #function on this problem.
