Discussion of Problem 1510. Order

Task 1510 - AV on test 7
Posted by Yuriy V. 14 Sep 2015 21:25
Could anyone helps me with test 7?

I wrote simple (dummy) solution - just store all input values in array - then sort it (qsort) - and write array[n/2].

I use free pascal.

On my PC program works correct. at least there no any runtime errors. I tested it with input N=1, 2, 3, 5, 1000, 500000. I enabled all checks like I/O, range check, stack check, overflow check, even init variables with garbage...

Could s/w get me any clue what can be wrong?

my last try - id 6409005
