Alphabetically sorted strings are read from input into a list. Complete the find$()$ function, which outputs range$\_$size, mid$\_$index, and the element at mid$\_$index:

Assign range$\_$size with the total number of list elements from first$\_$index to last$\_$index $($both inclusive$).$

Assign mid$\_$index with the result of dividing the sum of first$\_$index and last$\_$index by $2$ using floor division $(//).$
