If you're referring to the second sample test, the input is sc301s, the expected return value is c0s3s1, your current code returns s1cs30

strng='c0s3s1'
array=[4,0,3,1,5,2]

"c"=4
"0"=0
"s"=3
"3"=1
"s"=5
"1"=2
result=031scs

Ruby:

random tests should not have a fixed length of 10 for both string and array

Groovy Translation

Fair enough. I completely overlooked that

From the kata's description:

but do not begin or end the string with a dash mark.

Not a kata issue.

One of the weird sample tests uses 1 and expects 1, not -1-.

1 is an odd number and so the test should have dashes

Edit: forgot to mention this is the JavaScript version

for Java, I change parameter in function from int to long. There is a test where num = -2147483648
