# coding: utf-8
import copy
input_S =list(raw_input())
T = ""
reversed_S = copy.deepcopy(input_S)

reversed_S.reverse()

while(len(input_S)> 0):
    if input_S < reversed_S:
        T += input_S[0]
        input_S = input_S[1:]
        reversed_S= reversed_S[:-1]

    else:
        T += reversed_S[0]
        input_S = input_S[:-1]
        reversed_S= reversed_S[1:]
print T

(自分としては)珍しく回答例よりシンプルに書けた。
