Decoding V77873

The decoding of a natural number n is a string of characters such that every two digits of n represent a character. For example, the decoding of n = 6568 is AD, because the ASCII code of the character A is 65 and the ASCII character of the character D is 68. Notice that n has two groups of two digits: 65 and 68. Another example: the decoding of 65666768 is ABCD, since n is composed of 65, 66, 67, and 68.

It is necessary to implement the recursive function void decodificacio(int) with the following specification:

PRE: The input is an integer n such that:

1. n ≥ 65
2. n = d₁ d₂ d₃ d₄ … d_m−1 d_m.
3. m is even
4. for any pair of digits d_i d_i+1 (i odd) we have that 65 ≤ d_i d_i+1 ≤ 90.

POST: writes the decoding of n to the output channel cout.

Observation

Only recursive solutions are accepted.

IMPORTANT: You only need to submit the requested function, and possibly other necessary actions and functions. However, you must keep the type definitions and #includes.

Input

The input consists of a natural number n ≥ 65 such that n = d₁d₂d₃d₄ … d_m−1d_m m is even and for any pair of digits d_i d_i+1 such that i is odd, we have that 65 ≤ d_i d_i+1 ≤ 90.

Output

For each integer n, its decoding.
