Write a program that takes a number n and outputs a point−down triangle of height n and width 2n−1; the output for n = 6 would be: Enter a number: 6 *********** ********* ******* ***** *** *

Solution in Python Programming Language

height = int(input("Enter a number: "))
width = (2*height)-1
n = height
offset = 0
while (height > 0):
    print ' '*offset,"*"*width,"\n"
    height -= 1
    width = (2 * height) - 1
    offset = n - (height)
