Assume the availability of a method named makeline that can be passed a non-negative integer n and a character c and return a string consisting of n identical characters that are all equal to c. write a method named printtriangle that receives two integer parameters n and k. if n is negative the method does nothing. if n happens to be an even number, its value is raised to the next odd number (e. g. 4--> 5). then, when k has the value zero, the method prints a symmetric triangle of o's (the capital letter o) as follows: first a line of n o, followed by a line of n-2 o's (indented by one space), and then a line of n-4 o's (indented by two spaces), and so on. for example, if the method received 5,0 (or 4,0) it would print:
