题目描述

A string ss of length nn can be encrypted by the following algorithm:

  • iterate over all divisors of nn in decreasing order (i.e. from nn to 11 ),
  • for each divisor dd , reverse the substring s[1d]s[1 \dots d] (i.e. the substring which starts at position 11 and ends at position dd ).

For example, the above algorithm applied to the string ss ="codeforces" leads to the following changes: "codeforces" \to "secrofedoc" \to "orcesfedoc" \to "rocesfedoc" \to "rocesfedoc" (obviously, the last reverse operation doesn't change the string because d=1d=1 ).

You are given the encrypted string tt . Your task is to decrypt this string, i.e., to find a string ss such that the above algorithm results in string tt . It can be proven that this string ss always exists and is unique.

输入格式

The first line of input consists of a single integer nn ( 1n1001 \le n \le 100 ) — the length of the string tt . The second line of input consists of the string tt . The length of tt is nn , and it consists only of lowercase Latin letters.

输出格式

Print a string ss such that the above algorithm results in tt .
