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.

Constraints

The length of S is 2 or 3.

S consists of lowercase English letters.

Input

Input is given from Standard Input in the following format:

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

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