PROGRAMMING:Play dota II

In dota2, Cal the beggar can summon three elements: quas, wex, and exit. When you press Q, he will summon an ice element, press w to summon the thunder element, and press e to summon the fire element. The maximum number of all elements is 3, which means that when you already have 3 arbitrary elements, if you call another element, the first element will disappear and a new element will be born. At the same time, he also has a skill - Elemental call (R). Element call can cast different skills according to the number of elements you currently have. After casting skills, the elements will not disappear. When the number of elements is less than three, you cannot cast skills. For a more detailed explanation, see the example. Please print out what skills Carl has put according to his operation. If you can't put skills, output "fffk". The skill list is shown below:
###Input format:
A string containing only qwer and no more than 10 ^ 6 in length.
###Output format:
Each time Carl presses R, he outputs an answer, one line for each answer.
###Input example:
```in
EERERWRWRWRR
```
###Output example:
```out
FFFFFFFK
Sun Strike
Chaos Meteor
Alacrity
EMP
EMP
```
###Tips:
There is no sequence of states. For example, wee and ewe are the same as EEW
When using R for the first time, Carl's status is EE, so he can't use skills.
When R is used for the second time, Carl's status is EEE and can use sun strike
When R is used for the third time, Carl's status is EEW and can use chaos meteor
When R is used for the fourth time, Carl's status is eww and alacrity can be used
When using R for the fifth time, Carl's status is WWW and can use EMP
When using R for the sixth time, Carl's status is WWW and can use EMP
