Write a function String pyranid(int n ) that takes an integer rows as an argument, and returns a String that represents a pyramid that has zows height. For example, if rows is 5, printing the string that is returned should show: Exercise 2 Write a function String sidepyramid (int n) that takes the number of rows as an argument, and returns a string that represents a pyramid on its side. For example, if rows is 5 , printing the string will show: Exercise 3 Write a function string alternatingPyramid (int n) that takes a number of rows as an argument, and returns a string that represents a pyramid with alternating '' 1 ' and ' + ' symbols. For example, if rows is 6 , then printing the string will show: Hint: try attempting this without alternating at first Hint: separate the logic for spaces and asterisks. Also, highlight the pyramid using your mouse. What do you notice about the whitespace to the left and right side of the tree
