DE-code this Leader [4]

Hello members of the DE-coding club! So far, we have had DE-code this [1], The DE-coding competition [2], The DE-coding adventure [3], and, now DE-code this Leader [4]!!

How this works:

Well this is sort of like a competition, unlike the adventure one. So basically, everyone starts with 5 points. I post a code. The first to DE-code it posts it in this thread. If they did it correctly, they gain x point(s). If they did it incorrectly they lose y point(s). If it is incorrect, the first person who posted correctly will receive the x point(s) instead. If someone posted before you but you have a different answer, you can post. If someone posted before you with the same answer, you cannot post. The winner is the first person to 20 points. Once someone had achieved that, then the rest will be ranked 2-5th place depending on how many points they had. Hints may not be asked for, because they will not be received.

For each code I shall be posting what the x is, (how many you will get if solved correctly) and y (how many you will lose if solved incorrectly.)

Leader-board for points so far:
1- Lily Clarke (13pts)
2 - Hana Suzuki (10pts)
3 - Everyone else (5 pts)
4 - Ally Craig (2pts)
5 -

I will post the first code tomorrow, once a few more people see this. Remember, if you are in the club this is NOT compulsory, but it might be fun to take part.
