Problem Statement

You are given a string S of length 2 or 3 consisting of lowercase English letters. If the length of the string is 2, print it as is; if the length is 3, print the string after reversing it.

S

Output

If the length of S is 2, print S as is; if the length is 3, print S after reversing it.

Sample Input 1

abc

cba

As the length of S is 3, we print it after reversing it.

As the length of S is 2, we print it as is.

Solution in Julia (0.5.0) (judge verdict: Runtime Error)

function main()
	s = split(readline(), "")
	if length(s) == 3
		for i in 1:2
			print(s[i])
		end
	else
		for i in 0:3
			print(s[3-i])
		end
	end
	println()
end

main()
