Given an int variable n that has already been declared and initialized to a positive value, write a java program that prints the reverse triangle of asterisks with n asterisks on the first line (top of triangle), one less asterisk on the next level, and so on till 1 asterisk on the bottom level. (all asterisks aligned on the left, not centered in the middle, so you don’t need blanks. but think how you would have solved this problems if you’d need to center the triangle! )
