How to print an array of elements in reverse order not just single digit number but also multi-digit numbers.
[2, 5, 6 7]
It should print the array elements in reverse order as 7 6 5 2
by following a space for each number.
I already wrote the code for this.
puts "Enter the array elements"
arr = gets.strip
arr = arr.split(' ').map(&:to_i)
x = arr.reverse_each {|f| }
z = x.join(" ")
print z.reverse
That is cool with single digit numbers, how can I reverse the multi-digit numbers in an array of inputs given by the user input like:
[45, 76, 87 ] # this should reverse the array as `87 76 45`
[556, 674, 878 ] # this should reverse the array as `878 674 556`
[8797, 7347, 9374 ] # this should reverse the array as `9374 7374 8797`
If you like one-liners:
gets.strip.split(' ').reverse.join(' ')
This will take the input 1 2 3 45 678 9
and convert it to "9 678 45 3 2 1"
Input: [8797, 7347, 9374 ]
Output: "9374 7374 8797"
arr = gets.chomp
arr = arr.split(' ').map(&:to_i)
x = arr.reverse.join(' ')
print x
Use reverse
and join
chained and it should return a String
type that joined your reversed array.
