Hacker Challenge: Palindromic Pyramids
Let's create different pyramid patterns using nested loops.
We'll cover the following
In this lesson, we will write a program that prints pyramids with numbers and alphabets. So let’s start a discussion on the pyramid of numbers!
Pyramid of numbers
Write and run a program that prints the following shape:
Height: 5
1
121
12321
1234321
123454321
Look at the above example for Height: 5
, where we need to figure out the pattern in each line. Notice that the numbers are printed in ascending order and descending order from 1
to a number k
.
- In line 1, one number is printed.
- In line 2, two numbers are printed in ascending order and one in descending order.
- In line 3, three numbers are printed in ascending order and two in descending order.
Can you see a pattern based on the line number?
