Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Reference solution and fixed tests also ignore any situation where both person have
0yo
in age (which would be twice the age of the other, since0 * 2 = 0
):Reference solution is demonstrably wrong:
These two range will sum up to
365
as none of the ranges hit leap years.chai
/assert
) should be enabledC Translation
The Swift tests are still broken.
The sample tests fail by themselves independent of the solution code: https://i.imgur.com/qwh8jTm.png
The "attempt" random tests expect the wrong results for "8.2M ohms" ( https://i.imgur.com/21Xarxu.png ) and "4.1M ohms". ( https://i.imgur.com/ppBHn61.png )
Tests have a problem. They do not detect an error when there is a resistor value like "4.7M ohms". My code answered a wrong value and still passed the tests.
Node 18 (
mocha
+chai
) should be enabled (Refer this and this for more info)Ruby 3.0 should be enabled (Refer this & this for more detail)
mocha

) should be enabled (Refer this and this for more info)In Python, the special message and the
# -*- coding: utf-8 -*-
are not necessary anymore since only Python 3.6 is allowed.@tachyonlabs Anybody?..
Crystal version seems to require integer overflow in order to pass the tests. The tests should be updated to use
Int64
where appropriate.Well, I spent some times on this, and I'm sorry to agree with gopherati, the reference code is buggy.
After guessing a lot, I assumed my code is OK and so I passed the tests in force (trying until random being in my favor).
The problem with your code is that when oldest birthday is before youngest in the year (see spoiler comment below).
Also, while trying another way to do this, I got this error:
ValueError: day is out of range for month
To me, this can happen only with one of birthday being "02/29/Y".
Finally, the fact I passed the test in force means there isn't enough edge cases tests.
There should be at least every combinations of:
oldest_birthday < or == or > youngest_birthday,
"02/28" equal to one of, or before, or between, or after birthdays,
more or less than 365 days between births.
adding to the description a short example/representation of a tree could be a good idea, imo.
edit: rather than a representation, the statements of the definition of a small tree would be better: this way, the user will see that "undirected" is actually equivalent to "doubly linked" (for those who aren't familiar with graph nodes).
Java test cases should inlcude border examples as my solution is wrong and i have passed the kata.
Met the issue with one of test cases as @pjleejr mentioned
"yellow black green gold" which would be 4.0M
