2. Write a recursive function recHourGlassShape( that takes a character and two integers n and indent as parameters and prints an hour glass pattern using the character. The number of characters in the top line of the pattern and in the bottom line of the pattern (i.e. the biggest lines for each of the characters) is n. The indent parameter represents the indentation used in the first line of the pattern and in the last line of the pattern. The indentation increases in the top triangle (using the first character) and decreases in the bottom triangle (using the second character). If n is 0 or negative or one of the characters is the empty string, the function doesn't print anything. You should assume that the indent parameter will be non-negative (i.e. >- 0). The following shows several examples of patterns using different characters, values of n, and amount of indentation. >>>recHourGlassshape (*,10,0) >>>recHourGlassshape (' ,10,10) sss$ S$ sss$ SSSsSs$s >>> recHourGlassShape('$,0,10) >>>recHourGlassshape ('$,5,2) >>> recHourGlassshape(-,3,2)
