I get an error message that states the following, even though my code seems right.
expected 'N ffns bt,\nYr wrtng s mng th wrst '…' to equal 'N ffns bt,\nYr wrtng s mng th wrst '…'

PS. My code is in the replies :)
Please help me figure out where I am going wrong!

The test case has an issue in which the final '1' or '!' is removed in expected but not in my actual. Why is the test case removing the these characters when they are not vowels? My code is producing the correct output but its saying I have an issue

Thanks! Will try again

you are not required to (and should not) mutate the input matrix; your algo is wrong. try your function with e.g. [[1, 2], [3, 4]], it returns [ [ 1, 3, 1, 3 ], [ 2, 4, 2, 4 ] ], which is not the transpose of [[1, 2], [3, 4]]

JavaScript

Not anymore.

TypeError: Test.deepEqual is not a function
at Context. (test.js:34:6)

Approved.

My code works on mac terminal but it doesn't match output on here for some reason and I cannot figure out why

Scala translation

Yup, I haven't try to pass that expression directly to Wolfram. Was only trying to check my way of solution, my fault. Now I've found that for some scenarious it leeds to error... Thank you!
