How to Iterate over a Two Dimensional Array in Ruby - Step by Step Examples
How to Iterate over a Two Dimensional Array in Ruby ?
Answer
To iterate over a Two Dimensional Array in Ruby, you can use nested loops or methods like each or map.
✐ Examples
1 Iterating over a 2D Array with Nested Loops
In this example,
- We declare and initialize a 2D array named
matrix
. - We use nested loops to iterate over the rows and columns of the array.
- Inside the inner loop, we access and print each element of the array.
Ruby Program
matrix = [[1, 2], [3, 4], [5, 6]]
matrix.each do |row|
row.each do |element|
print "#{element} "
end
puts
end
Output
1 2 3 4 5 6
2 Iterating over a 2D Array with 'each' Method
In this example,
- We declare and initialize a 2D array named
matrix
. - We use the
each
method to iterate over each row of the array. - Inside the block, we use the
each
method again to iterate over each element of the row and print the element.
Ruby Program
matrix = [[1, 2], [3, 4], [5, 6]]
matrix.each { |row| row.each { |element| print "#{element} " }; puts }
Output
1 2 3 4 5 6
