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.
wtf🤯
Nice dude I spent so much time on this problem
n>0 is treated as 1 if True. when passed to sum() is the same as doing sum(1 if n>0...). Althoug I've read somewhere it's not good practice to use booleans as integers since you are violating some principle. Can't recall which one now.
there are only a few cases in which these smileys are created, if we just create them into one list and then just check them and run the sum function it would be more faster for these test cases.
What happens if prod is MAX_UNSIGNED_LONG_LONG?
The while loop will never break (or you'll get ull overflow error)
don't know regex so didn't take this approach!
strings are ordered lexicographically
and if you attempt to compare a string to an int then whichever one of them you ask they'll tell you they don't know which comes first. (operators boil down to method calls on one of the operands. you're asking one of the values if it's smaller than the other)
javascript on the other hand, is a mistake, and will convert mixed values into a single type and then compare for you. all friendly and with a smile on its face. "friendly" here really just means it did something other than what you said, which is a great way to make your code full of difficult to find bugs.
hi natan, could you please explain how the code treats this?
that is not what happens, for example,
'9'
is not less than'10'
languages shouldn't guess what's meant, they should do what is said
good to know that you could use c < '5' and it will automatically treat the string value to int, instead of using the int() function on the individual string value.
unreadable
I did that but with AI help. Don't know what challenged me so much with this one
can someone help me out in understanding this? how does it work?
It looks like it counts the number of characters.
it is nice use of functions. However, somehow makes the code unreadable.
Broke another keyboard trying to find a solution without mapping 4x and 9x numerals but here you are! Cheers, legend.
