Thanks for the heads up and the solution to it ;)
fixed 👍

the image is gone yet again >:) though it can still be viewed by visiting the link. After some research, it seems Google Drive now forbids the /uc URL scheme to be used for embedding.
In order for it to embed, the link should be changed from:

https://drive.google.com/uc?uc?export=view&id=1iphtIoYbHFkXK1GLCcM5_lptiBie6I_m

to:

this is how Java works, dateFormat.parse() can throw a ParseException, you must either catch it or declare your method as throwing a ParseException. option 2 is not possible, because the tests do not expect your method to throw an error. So you have to use try/catch

Right, it's not always true. Clarified it in the description

C translation

Every year contains of 52 (53 for leap years) calendar weeks.

this is not true, for example 2015 has 53 weeks and is not a leap year; while 2012 is a leap year and has 52 weeks. The leap week does not systematically fall within the leap year.

.every function will stop on first falsy value

expected [ Array(3) ] to deeply equal [ Array(3) ]

missing the config threshold limit thing (sample tests at least)

I thought my solution is the ugliest...

thanks for the hint - uploaded again
