Published on 02 October 2024 (Updated: 02 October 2024)
Welcome to the Palindromic Number in Ruby page! Here, you'll find the source code for this program as well as a description of how the program works.
Current Solution
# print true, if input is a non-negative palindrome number
if ARGV.empty?
puts "Usage: please input a non-negative integer"
exit
else
begin
string1 = ARGV[0]
num = Integer(string1)
rescue ArgumentError
puts "Usage: please input a non-negative integer"
exit
end
if num < 0
puts "Usage: please input a non-negative integer"
exit
end
# end validations for empty input, non-number and negative number
reverse_no = 0
save = num
while (save > 0)
last_digit = save % 10
reverse_no = (reverse_no *10) + last_digit
save /=10
end
if num == reverse_no
print("true")
else
print("false")
end
end
