Question 2
Aika likes taking photographs of her cat and posting them on social media.
The dates on the original photographs are 24 March 2021, 14 June 2021 and 28 August 2021.
To manage them easily, she will name each photograph so that the computer stores the photographs in order from oldest to newest. Here are some naming methods Aika considers (the Vietnamese month-name tokens are preserved because their alphabetical order is part of the task):
- MEO_Thangtam_19_2021
- MEO_19_8_2021
- MEO_2021_Thangtam_19
- MEO_2021_08_19
- MEO_19_Thangtam_2021
- MEO_19_08_2021
- MEO_2021_19_8
- MEO_2021_8_19
The computer stores photographs by name in order from A to Z and from 0 to 9. How many of these naming methods can Aika use?
