What means sqrt ranges?

Lol, I just tried to divied by zero...

Why is my code running good in visual studio and get all tests, but in codewars I have:
UndefinedBehaviorSanitizer:DEADLYSIGNAL
==1==ERROR: UndefinedBehaviorSanitizer: FPE on unknown address 0x000000425719 (pc 0x000000425719 bp 0x7ffc046ee768 sp 0x7ffc046ee290 T1)
==1==WARNING: invalid path to external symbolizer!
==1==WARNING: Failed to use and restart external symbolizer!

Is anybody know?

thank you

Why if my result valid I get 12000ms, but if I'll add one character to result then you tell me that that's wrong too quick.

If someone tell me why it can be, I will be very grateful. I could replace double spaces on "Z", "V", "A", and I think on any symbol or string, but not on singly space.

Idiot kata. I did everything, but couldn't delete fucking double spaces (" "), because:
unmap_chunk(): invalid pointer

It means fuck you, you can't delete it.
