"You are given a string of n lines, each substring being n characters long." If you have 8 lines, you must have 8 sized string in each line.

Got something similar in Powershell:

ARR : zone abigail theta form libe zas ;k : 2
actual abigailtheta
expect abigailtheta
*
ARR : ejjjjmmtthh zxxuueeg aanlljrrrxx dqqqaaabbb oocccffuucccjjjkkkjyyyeehh ;k : 1
actual oocccffuucccjjjkkkjyyyeehh
expect oocccffuucccjjjkkkjyyyeehh
*
ARR : ;k : 3
actual
expect

problem with testing after final submit:

should pass basic tests
Log
Testing: zone,abigail,theta,form,libe,zas,theta,abigail, 2
Actual: abigailtheta
Expect: abigailtheta

Testing: ejjjjmmtthh,zxxuueeg,aanlljrrrxx,dqqqaaabbb,oocccffuucccjjjkkkjyyyeehh, 1
Actual: oocccffuucccjjjkkkjyyyeehh
Expect: oocccffuucccjjjkkkjyyyeehh

after cliking "ATTEMPT"

Actual: arp, live, strong
Expect: arp, live, strong

Actual: arp
Expect: arp

@steffan153 Nothing is visible. There is a red arrow to left of "KataTest". It's expand/collapse feature. But expanding it doesn't show anything.
@mahesh2492 Were you able to proceed so far ?

@Technetium_Phenol Oh, C'mon :D It's 21st century, forget Fortran and come to Scala :D

Just faced 1 was not equal to -1 error on final 'Attemptstage. After debugging (adding print statements to check input parameters) found out thatkparameter value was< 0` Just shared a hint here to help someone ;)

@mahesh2492 You can add a print statement for any random failing test by if condition to print all input parameters as well as your return value.
print your return value to find out which test is failing and then add checks accordingly.

Okay, that was indeed overflow issue. My buffer was initialized as Int. Thanks for quick response!

@sitetester: I already gave you an answer. Ask yourself, why are you returning a negative number? (what makes it happen and how can you avoid it?)

There's 276 scala completions, so it's not an issue with kata itself.

Same issue -1961650628 did not equal 2333316668 for scala

How could negative number be correct answer? :P Sounds like overflow issue, but I don't do scala, so idk.
