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.

I've found my source of error and passed all the tests.
However, as floating point numbers are not exactly for most decimal fractional numbers, the tests should allow some error margins. Comparing with a reasonable error margin is also good practice in real program when floats are compared. Rust has
assert_approx_eqfor this. (use assert_approx_eq::assert_approx::eq)This comment is hidden because it contains spoiler information about the solution
(Scala) Some random test give me a feedback say that the expected result for heightEq() would be
-16.0t^2 + 0.000t + ????.While the description explicitly says: "NOTE: Some solutions were invalidated because I added tests for situations where the starting height is 0, in which case the equation for height would be in the form h(t) = -16.0t^2 + vt where v represents the initial vertical velocity.", shouldn't the
0second term be omitted?Also, why the second term has three decimal points?
How would a number (1) or a symbole (.) or a blank sort with letters, or with each other, considering sorting between lettes are case insensitive?
