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 Input is given from Standard Input in the following format: $S$ [samples]
