How to print Left Half Pyramid Pattern in Ruby

How to print Left Half Pyramid Pattern in Ruby ?

Answer

To print the Left Half Pyramid Pattern in Ruby, we use nested loops where the outer loop controls the rows and the inner loop prints spaces and stars.

✐ Examples

1 Left Half Pyramid Pattern

In this example,

We define the size of the pyramid, n, which is set to 5 in this example.
We use two nested loops: an outer loop to handle rows and an inner loop to print spaces and stars.
The outer loop runs from 1 to n, controlling the number of rows.
The inner loop in Ruby prints spaces based on the difference between n and the current row, followed by stars equal to the current row number.
This combination of loops and print statements creates the Left Half Pyramid Pattern.

Ruby Program

n = 5
(1..n).each do |i|
  puts ' ' * (n - i) + '*' * i
end

Output

    *
   **
  ***
 ****
*****
