Description

Write a program to find the "relative string" $s_1$ of a given string $s$. The relative string $s_1$ is defined as follows: the first character of $s_1$ is obtained by adding the ASCII values of the first and second characters of $s$; the second character of $s_1$ is obtained by adding the ASCII values of the second and third characters of $s$; and so on until the second-to-last character of $s$. The last character of $s_1$ is obtained by adding the ASCII values of the last character of $s$ and the first character of $s$.

Input Format

One line containing a string with length between $2$ and $100$ inclusive. The ASCII value of each character in the string does not exceed $63$.

Output Format

Output one line containing the transformed relative string. It is guaranteed that the output will be a single line.
