get$\_$row$($str$,$ int$)->$ strThe first parameter represents a puzzle and the second represents a row number. Return the letters in the row corresponding to the row number, excluding the newline character. The letters should be in the same order as they appear in the puzzle. The first row is row number $0.$For example, if our puzzle is the string 'abcd

efgh

ijkl

$\text{'},$ and we wanted to find row $1($which contains $4$ letters$),$ we would expect the string 'efgh' to be returned.Hint: you will need to call on one of the helper functions provided in the starter code.
