To print Pascal's Triangle Pattern in Ruby, you can use nested loops where the outer loop controls the rows and the inner loop calculates the values for each row based on the binomial coefficient formula.
In this example,
n
to represent the number of rows in Pascal's triangle.pascal
to store the triangle values.def print_pascals_triangle(n)
pascal = Array.new(n) { Array.new(n, 0) }
n.times do |i|
(i + 1).times do |j|
if j == 0 || j == i
pascal[i][j] = 1
else
pascal[i][j] = pascal[i - 1][j - 1] + pascal[i - 1][j]
end
print pascal[i][j], ' '
end
puts
end
end
rows = 5
print_pascals_triangle(rows)
1 1 1 1 2 1 1 3 3 1 1 4 6 4 1
In this tutorial, we learned How to print Pascal's Triangle Pattern in Ruby language with well detailed examples.
