Strings-Difference in Ascii Codes [codingblocks]

Take as input S, a string. Write a program that inserts between each pair of characters the difference between their ascii codes and print the ans.

Input Format
String

Constraints
Length of String should be between 2 to 1000.

Output Format
String

Sample Input
acb

 
Sample Output
a2c-1b

 
Explanation
For the sample case, the Ascii code of a=97 and c=99 ,the difference between c and a is 2.Similarly ,the Ascii code of b=98 and c=99 and their difference is -1. So the ans is a2c-1b.
