Problem Statement
On some day in January $2018$, Takaki is writing a document. The document has a column where the current date is written in yyyy/mm/dd
format. For example, January $23$, $2018$ should be written as 2018/01/23
.
After finishing the document, she noticed that she had mistakenly wrote 2017
at the beginning of the date column. Write a program that, when the string that Takaki wrote in the date column, $S$, is given as input, modifies the first four characters in $S$ to 2018
and prints it.
Constraints
- $S$ is a string of length $10$.
- The first eight characters in $S$ are
2017/01/
. - The last two characters in $S$ are digits and represent an integer between $1$ and $31$ (inclusive).
Input

Output
Replace the first four characters in $S$ with 2018
and print it.
