this error happens only in sample tests, random tests are working fine

okay stop flexing

I had another onstance of this, one (I assume random), test fails. But if I try again and don't get that test I pass. The test that catches my code is:
['69', '83', '53', '62', '52', '10', '79', '30', '33', '89', '26', '45', '75', '51', '25', '73', '52', '100', '82', '6', '20']
'101002025263033455152525362669737579828389' should equal '100102025263033455152525362669737579828389'

The test ['10','100'] causes my code to fail.

I was a great trip. You lived in a amazing place.)

thx

Piece of cake:)

Only correct because n < 100 in test case

so there is a new fixed test to add. ;) And the author should raise up the number of random tests: 20 isn't enough (as just demonstrated by mD4ndr3. 100 is a minimum, for proper random testing, generally.

Thanks!
